But now I'm having troubles with building the executables from the same package that depend on this library. My "test case" is fribidi. In short: 1) I added -no-undefined to libfribidi_la_LDFLAGS in Makefile.in (there's only one, no subdirs). 2) I added an empty main function to one of the src .c files: +int main () +{ return 0; } dlltool seems to build cygfribidi-0.dll properly, then make continues to build fribidi.exe, which depends on libfribidi, and the following happens: /bin/sh ./libtool --mode=link gcc -O2 -Wall -lm -o fribidi.exe fribidi_main.o getopt.o getopt1.o libfribidi.la -L. -lfribidi generating import library for `cygfribidi-0.dll' dlltool --as=as --dllname cygfribidi-0.dll --def .libs/cygfribidi-0.dll-def --output-lib .libs/libimp-cygfribidi-0.a gcc -O2 -Wall -o .libs/fribidi.exe fribidi_main.o getopt.o getopt1.o - -L/home/Yaakov/devel/testing/fribidi/fribidi-0.10.4/.build .libs/libimp-cygfribidi-0.a fu000001.o(.idata$3+0xc): undefined reference to '__libs_libimp_cygfribidi_0_a_iname' nmth000000.o(.idata$4+0x0): undefined reference to `__nm__fribidi_version_info' Info: resolving _fribidi_version_info by linking to __imp__fribidi_version_info (auto-import) collect2: ld returned 1 exit status make: *** [fribidi.exe] Error 1 So what am I missing now? Or is this a problem with the code?
