I am having trouble with building the gcc 4.5.1 with --enable-plugin on Cygwin. The configure string is "--enable-plugin --enable-languages=c,c++ --disable-bootstrap". The error is , checking for -rdynamic... objdump: conftest: not a dynamic object no checking for library containing dlopen... none required checking for -fPIC -shared... no configure: error: Building GCC with plugin support requires a host that supports -fPIC, -shared, -ldl and -rdynamic. make[1]: *** [configure-gcc] Error 1
When I jump the -fPIC checking, it's success. And then failed when building a gcc plugin, print following, plugin.c:1:0: warning: -fPIC ignored for target (all code is position independent) /tmp/ccU93aXF.o:plugin.c:(.text+0xd1): undefined reference to `_build3_stat' /tmp/ccU93aXF.o:plugin.c:(.text+0xff): undefined reference to `_gimple_assign_single_p' .....
