This has nothing to do with gcc, but people ask us about it a lot. ! Code like this: ! #include ! ! FILE *yyin = stdin; ! ! will not compile with GNU libc (Linux libc6), because stdin is not a ! constant. This was done deliberately, in order for there to be no ! limit on the number of open FILE objects. It is surprising for people ! used to traditional Unix C libraries, but it is permitted by the C ! standard. ! ! This construct commonly occurs in code generated by old versions of ! lex or yacc. We suggest you try regenerating the parser with a current ! version of flex or bison, respectively. In your own code, the ! appropriate fix is to move the initialization to the beginning of ! main. ! ! There is a common misconception that the GCC developers are ! responsible for GNU libc. These are in fact two entirely separate ! projects. The appropriate place to ask questions relating to GNU libc ! is [77]libc-alpha@sourceware.cygnus.com. ! _________________________________________________________________ ! ! Why can't I use #if here? ! ! Let me guess... you wrote code that looks something like this: ! memcpy(dest, src, ! #ifdef PLATFORM1 ! 12 ! #else ! 24 ! #endif ! ); ! ! and you got a whole pile of error messages: ! test.c:11: warning: preprocessing directive not recognized within macro arg ! test.c:11: warning: preprocessing directive not recognized within macro arg ! test.c:11: warning: preprocessing directive not recognized within macro arg ! test.c: In function `foo': ! test.c:6: undefined or invalid # directive ! test.c:8: undefined or invalid # directive ! test.c:9: parse error before `24' ! test.c:10: undefined or invalid # directive ! test.c:11: parse error before `#' ! ! The problem, simply put, is that GCC's preprocessor does not allow you ! to put #ifdef (or any other directive) inside the arguments of a ! macro. Your C library's string.h happens to define memcpy as a macro - ! this is perfectly legitimate. The code therefore will not compile. ! ! We have two good reasons for not allowing directives inside macro ! arguments. First, it is not portable. It is "undefined behavior" ! according to the C standard; that means different compilers will do ! different things with it. Some will give you errors. Some will dump ! core. Some will silently mangle your code - you could get the ! equivalent of ! memcpy(dest, src, 1224); ! ! from the above example. A very few might do what you expected it to. ! We therefore feel it is most useful for GCC to reject this construct ! immediately so that it is found and fixed. ! ! Second, it is extraordinarily difficult to implement the preprocessor ! such that it does what you would expect for every possible directive ! found inside a macro argument. The best example is perhaps ! #define foo(arg) ... arg ... ! foo(blah ! #undef foo ! blah) ! ! which is impossible to implement in portable C without leaking memory. ! Allowing only a subset of directives would be confusing. ! ! It is always possible to rewrite code which uses conditionals inside ! macros so that it doesn't. You could write the above example ! #ifdef PLATFORM1 ! memcpy(dest, src, 12); ! #else ! memcpy(dest, src, 24); ! #endif ! ! This is a bit more typing, but I personally think it's better style in ! addition to being more portable. _________________________________________________________________ Miscellaneous *************** Snapshots, how, when, why *** 685,691 **** code or even fail to build.

    Why can't I initialize a static variable with stdin?

    + +

    This has nothing to do with gcc, but people ask us about it a + lot. Code like this:

    + + 
    +   #include <stdio.h>
+ 
+   FILE *yyin = stdin;
+
    + +

    will not compile with GNU libc (Linux libc6), because + stdin is not a constant. This was done deliberately, in + order for there to be no limit on the number of open FILE objects. It + is surprising for people used to traditional Unix C libraries, but it + is permitted by the C standard.

    + +

    This construct commonly occurs in code generated by old versions of + lex or yacc. We suggest you try regenerating the parser with a + current version of flex or bison, respectively. In your own code, the + appropriate fix is to move the initialization to the beginning of + main.

    + +

    There is a common misconception that the GCC developers are + responsible for GNU libc. These are in fact two entirely separate + projects. The appropriate place to ask questions relating to GNU libc + is libc-alpha@sourceware.cygnus.com. +

    + +
    +

    Why can't I use #if here?

    + +

    Let me guess... you wrote code that looks something like this:

    + 
    +   memcpy(dest, src,
+ #ifdef PLATFORM1
+ 	 12
+ #else
+ 	 24
+ #endif
+ 	);
+
    +

    and you got a whole pile of error messages:

    + 
    + test.c:11: warning: preprocessing directive not recognized within macro arg
+ test.c:11: warning: preprocessing directive not recognized within macro arg
+ test.c:11: warning: preprocessing directive not recognized within macro arg
+ test.c: In function `foo':
+ test.c:6: undefined or invalid # directive
+ test.c:8: undefined or invalid # directive
+ test.c:9: parse error before `24'
+ test.c:10: undefined or invalid # directive
+ test.c:11: parse error before `#'
+
    + +

    The problem, simply put, is that GCC's preprocessor does not allow + you to put #ifdef (or any other directive) inside the arguments of a + macro. Your C library's string.h happens to define + memcpy as a macro - this is perfectly legitimate. The code + therefore will not compile.

    + +

    We have two good reasons for not allowing directives inside + macro arguments. First, it is not portable. It is "undefined + behavior" according to the C standard; that means different + compilers will do different things with it. Some will give you + errors. Some will dump core. Some will silently mangle your code - + you could get the equivalent of

    + 
    + 	memcpy(dest, src, 1224);
+
    +

    from the above example. A very few might do what you expected it + to. We therefore feel it is most useful for GCC to reject this + construct immediately so that it is found and fixed.

    + +

    Second, it is extraordinarily difficult to implement the + preprocessor such that it does what you would expect for every + possible directive found inside a macro argument. The best example is + perhaps

    + 
    + #define foo(arg) ... arg ...
+ foo(blah
+ #undef foo
+ blah)
+
    +

    which is impossible to implement in portable C without + leaking memory. Allowing only a subset of directives would be + confusing.

    + +

    It is always possible to rewrite code which uses conditionals + inside macros so that it doesn't. You could write the above + example

    + 
    + #ifdef PLATFORM1
+    memcpy(dest, src, 12);
+ #else
+    memcpy(dest, src, 24);
+ #endif
+
    +

    This is a bit more typing, but I personally think it's better style + in addition to being more portable.

Nobody with ! both 107058-01 and 106950-03 installed has reported the bug with ! GCC and Sun's dynamic linker. This last course of action is ! riskiest, for two reasons. First, you must install 106950 on all ! hosts that run code generated by GCC; it doesn't suffice to ! install it only on the hosts that run GCC itself. Second, Sun says ! that 106950-03 is only a partial fix for bug 4210064, but Sun ! doesn't know whether the partial fix is adequate for GCC.

    AIX Make frequently has problems with GCC makefiles. GNU Make 3.76 or newer is recommended to build on this platform.

    +

    Errors involving "alloca" when building GCC generally are due + to an incorrect definition of CC in the Makefile or mixing files + compiled with the native C compiler and GCC. During the stage1 phase of + the build, the native AIX compiler must be invoked as "cc" + (not "xlc"). Once configure has been informed of + "xlc", one needs to use "make distclean" to remove the + configure cache files and ensure that $CC environment variable + does not provide a definition that will confuse configure. + If this error occurs during stage2 or later, then the problem most likely + is the version of Make (see above).

    +

    Sun patch 107058-01 (1999-01-13) for SPARC Solaris 7 triggers a bug in the dynamic linker. This problem (Sun bug 4210064) affects GCC 2.8 ! and later, including all EGCS releases. To avoid this problem, do not ! install Sun patch 107058-01 until after Sun releases a patch for bug ! 4210064. Sun has a fix for this bug but (as of 1999-06-24) has not ! yet released it as a patch.

    A bug in the SunOS4 linker will cause it to crash when linking -fPIC compiled - objects (and will therefore not allow you to build shared libraries).

    !

    To fix this problem you can either use the most recent version of binutils or ! get the latest SunOS4 linker patch (patch ID 100170-10) from Sun's patch site.

    *-*-solaris*

    + +

    Starting with Solaris, Sun does not ship a C compiler any more. To + bootstrap and install GCC you first have to install a pre-built + compiler, for example from + http://www.sunfreeware.com.

    + +

    Sun as 4.X is broken in that it cannot cope with long symbol names. + A typical error message might look similiar to the following: +

    + /usr/ccs/bin/as: "/var/tmp/ccMsw135.s", line 11041: error: can't compute + value of an expression involving an external symbol. +
    + See the How to work around too long C++ + symbol names? FAQ entry for further information.

    sparc-sun-solaris2.7

    Sun patch 107058-01 (1999-01-13) for SPARC Solaris 7 triggers a bug in the dynamic linker. This problem (Sun bug 4210064) affects GCC 2.8 ! and later, including all EGCS releases. Sun formerly recommended ! 107058-01 for all Solaris 7 users, but around 1999-09-01 it started to ! recommend it only for people who use Sun's compilers.

    ! !

    Here are some workarounds to this problem: !

      !
    • Do not install Sun patch 107058-01 until after Sun releases a ! complete patch for bug 4210064. This is the simplest course to take, ! unless you must also use Sun's C compiler. Unfortunately 107058-01 ! is preinstalled on some new Solaris-based hosts, so you may have to ! back it out.
      • ! !
    • Copy the original, unpatched Solaris 7 ! /usr/ccs/bin/as into ! /usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.1/as, ! adjusting the latter name to fit your local conventions and software ! version numbers.
      • ! !
    • Install Sun patch 106950-03 (1999-05-25) or later. Nobody with ! both 107058-01 and 106950-03 installed has reported the bug with GCC ! and Sun's dynamic linker. This last course of action is riskiest, ! for two reasons. First, you must install 106950 on all hosts that ! run code generated by GCC; it doesn't suffice to install it only on ! the hosts that run GCC itself. Second, Sun says that 106950-03 is ! only a partial fix for bug 4210064, but Sun doesn't know whether the ! partial fix is adequate for GCC. Revision -08 or later should fix ! the bug, but (as of 1999-10-06) it is still being tested.
