------- Comment #7 from dannysmith at users dot sourceforge dot net 2008-05-11 22:46 ------- Following is with mingw but it applies to cygwin as well
This is the command line from log for FAILing 22_locale/locale/cons/unicode.cc Executing on host: /develop/svn/trunk/build/./gcc/g++ -shared-libgcc -B/develop/svn/trunk/build/./gcc -nostdinc++ -L/develop/svn/trunk/build/mingw32/libstdc++-v3/src -L/develop/svn/trunk/build/mingw32/libstdc++-v3/src/.libs -L/develop/svn/trunk/build/mingw32/winsup/mingw -L/develop/svn/trunk/build/mingw32/winsup/w32api/lib -isystem /develop/svn/trunk/src/winsup/mingw/include -isystem /develop/svn/trunk/src/winsup/w32api/include -B/mingw/mingw32/bin/ -B/mingw/mingw32/lib/ -isystem /mingw/mingw32/include -isystem /mingw/mingw32/sys-include -g -O2 -D_GLIBCXX_ASSERT -fmessage-length=0 -ffunction-sections -fdata-sections -g -O2 -g -O2 -DLOCALEDIR="." -nostdinc++ -I/develop/svn/trunk/build/mingw32/libstdc++-v3/include/mingw32 -I/develop/svn/trunk/build/mingw32/libstdc++-v3/include -I/develop/svn/trunk/src/libstdc++-v3/libsupc++ -I/develop/svn/trunk/src/libstdc++-v3/include/backward -I/develop/svn/trunk/src/libstdc++-v3/testsuite/util -Wl,--gc-sections /mingw/lib/libiconv.a /develop/svn/trunk/src/libstdc++-v3/testsuite/22_locale/locale/cons/unicode.cc -include bits/stdc++.h ./libtestc++.a -lm -o ./unicode.exe (timeout = 600) Note that although the correct libiconv "/mingw/lib/libiconv.a" is passed to linker, it is passed *before* the objects and libraries that reference libiconv symbols. With PE-COFF, the order of objects really does matter and since the libiconv symbols have not yet been referenced when the linker looks at the lib, the symbols are not resolved. They are not resolved lazily as is possible in ELF Danny -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36211
