Hello Has anyone encountered this when compiling gcc from source? libgomp doesn't build due to xgcc missing I got latest git, did ./configure --disable-multilib make html It gets stuck here: checking whether make supports nested variables... yes /home/jonny/code/repos/gcc_tests/gcc_doc/libgomp/configure: line 3520: /home/jonny/code/repos/gcc_tests/gcc_doc/host-x86_64-pc-linux-gnu/gcc/xgcc: No such file or directory checking for x86_64-pc-linux-gnu-gcc... /home/jonny/code/repos/gcc_tests/gcc_doc/host-x86_64-pc-linux-gnu/gcc/xgcc -B/home/jonny/code/repos/gcc_tests/gcc_doc/host-x86_64-pc-linux-gnu/gcc/ -B/usr/local/x86_64-pc-linux-gnu/bin/ -B/usr/local/x86_64-pc-linux-gnu/lib/ -isystem /usr/local/x86_64-pc-linux-gnu/include -isystem /usr/local/x86_64-pc-linux-gnu/sys-include checking whether the C compiler works... no configure: error: in `/home/jonny/code/repos/gcc_tests/gcc_doc/x86_64-pc-linux-gnu/libgomp': configure: error: C compiler cannot create executables See `config.log' for more details make[1]: *** [Makefile:23679: configure-target-libgomp] Error 1 make[1]: Leaving directory '/home/jonny/code/repos/gcc_tests/gcc_doc' make: *** [Makefile:1456: do-html] Error 2 I tried with: ./configure --disable-multilib --disable-libgomp but it just stops at the next checking for x86_64-pc-linux-gnu-gcc... /home/jonny/code/repos/gcc_tests/gcc_doc/host-x86_64-pc-linux-gnu/gcc/xgcc -B/home/jonny/code/repos/gcc_tests/gcc_doc/host-x86_64-pc-linux-gnu/gcc/ -B/usr/local/x86_64-pc-linux-gnu/bin/ -B/usr/local/x86_64-pc-linux-gnu/lib/ -isystem /usr/local/x86_64-pc-linux-gnu/include -isystem /usr/local/x86_64-pc-linux-gnu/sys-include checking for suffix of object files... configure: error: in `/home/jonny/code/repos/gcc_tests/gcc_doc/x86_64-pc-linux-gnu/libstdc++-v3': configure: error: cannot compute suffix of object files: cannot compile ee `config.log' for more details make[1]: *** [Makefile:17042: configure-target-libstdc++-v3] Error 1 Thanks, Jonny

Are you sure you ran configure in an empty dir, not one you'd already fouled up with previous configurations or previous 'make html' commands? You should start in a completely empty directory. And I assume ../gcc_doc is not the same directory as . The errors you're getting should not happen unless you've messed up the configure step somehow. > > $ make all-gcc > > make[1]: Entering directory '/home/jonny/code/repos/gcc_tests/gcc_build/gcc' > g++ -std=c++11 -c -g -O2 -DIN_GCC-fno-exceptions -fno-rtti > -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings > -Wcast-qual -Wmissing-format-attribute -Wconditionally-supported > -Woverloaded-virtual -pedantic -Wno-long-long -Wno-variadic-macros > -Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE -I. > -Ibuild -I../../gcc_doc/gcc -I../../gcc_doc/gcc/build > -I../../gcc_doc/gcc/../include -I../../gcc_doc/gcc/../libcpp/include \ > -o build/genmodes.o ../../gcc_doc/gcc/genmodes.cc > In file included from ../../gcc_doc/gcc/bconfig.h:3, > from ../../gcc_doc/gcc/genmodes.cc:20: > ../../gcc_doc/gcc/auto-host.h:2717:16: error: declaration does not declare > anything [-fpermissive] > 2717 | #define rlim_t long > |^~~~ > In file included from ../../gcc_doc/gcc/genmodes.cc:21: > ../../gcc_doc/gcc/system.h:500:14: error: conflicting declaration of C > function ‘void* sbrk(int)’ > 500 | extern void *sbrk (int); > | ^~~~ > In file included from ../../gcc_doc/gcc/system.h:302: > /usr/include/unistd.h:1076:14: note: previous declaration ‘void* > sbrk(intptr_t)’ > 1076 | extern void *sbrk (intptr_t __delta) __THROW; > | ^~~~ > ../../gcc_doc/gcc/system.h:508:14: error: ambiguating new declaration of > ‘char* strstr(const char*, const char*)’ > 508 | extern char *strstr (const char *, const char *); > | ^~ > In file included from /usr/include/c++/13/cstring:42, > from ../../gcc_doc/gcc/system.h:241: > /usr/include/string.h:343:1: note: old declaration ‘const char* strstr(const > char*, const char*)’ > 343 | strstr (const char *__haystack, const char *__needle) __THROW > | ^~ > ../../gcc_doc/gcc/system.h:556:20: error: conflicting declaration of C > function ‘const char* strsignal(int)’ > 556 | extern const char *strsignal (int); > |^ > /usr/include/string.h:478:14: note: previous declaration ‘char* > strsignal(int)’ > 478 | extern char *strsignal (int __sig) __THROW; > | ^ > In file included from ../../gcc_doc/gcc/system.h:729: > ../../gcc_doc/gcc/../include/libiberty.h:112:14: error: ambiguating new > declaration of ‘char* basename(const char*)’ > 112 | extern char *basename (const char *) ATTRIBUTE_RETURNS_NONNULL > ATTRIBUTE_NONNULL(1); > | ^~~~ > /usr/include/string.h:537:26: note: old declaration ‘const char* > basename(const char*)’ > 537 | extern "C++" const char *basename (const char *__filename) > | ^~~~ > make[1]: *** [Makefile:2987: build/genmodes.o] Error 1 > make[1]: Leaving directory '/home/jonny/code/repos/gcc_tests/gcc_build/gcc' > make: *** [Makefile:4996: all-gcc] Error 2 > > > Kind regards, Jonny

Thanks. Committed as follows.

* fileline.c: Include if available.
(windows_get_executable_path): New static function.
(fileline_initialize): Call windows_get_executable_path.
* configure.ac: Checked for windows.h
* configure: Regenerate.
* config.h.in: Regenerate.
