I have problems compiling DLLs with -mno-cygwin flag, using libtool. Command is: libtool --mode=link --tag=CXX g++ -rpath /Projects/Tests/libtool -mno-cygwin -no-undefined -o libcommon.la common.lo Output: rm -fr .libs/libcommon.a .libs/libcommon.la .libs/libcommon.lai g++ -shared -nostdlib /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/crtbegin.o .libs/common.o -L/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3 -L/usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/../../.. -lstdc++ -lgcc -lcygwin -luser32 -lkernel32 -ladvapi32 -lshell32 -lgcc /usr/lib/gcc-lib/i686-pc-cygwin/3.3.3/crtend.o -mno-cygwin -o .libs/cygcommon-0.dll -Wl,--image-base=0x10000000 -Wl,--out-implib,.libs/libcommon.dll.a ar cru .libs/libcommon.a common.o ranlib .libs/libcommon.a creating libcommon.la (cd .libs && rm -f libcommon.la && ln -s ../libcommon.la libcommon.la) As U can see... it automatically passes -lcygwin flag to the linker(g++). When cygcheck'ing resulting DLL it lists cygwin DLL as one of its dependencies. I heard somewhere that cygwin is requierd for DLL initialisation, is it true? The interesting thing is that linking against resulting DLL with so-called "-mno-cygwin -lcygwin" mix results in program startup failure(no errors, it just hangs). Any ideas on how to create cygwin independent DLL with libtool? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
