To install its shared library, the luajit Makefile does:
cd src && test -f $(FILE_SO) && \
$(INSTALL_X) $(FILE_SO) $(INSTALL_DYN) && \
$(LDCONFIG) $(INSTALL_LIB) && \
$(SYMLINK) $(INSTALL_SONAME) $(INSTALL_SHORT1) && \
$(SYMLINK) $(INSTALL_SONAME) $(INSTALL_SHORT2) || :
This means that if ldconfig doesn't work or isn't available on the
system, it won't create the libluajit-5.1.so -> libluajit-5.1.so.5.2.0
symbolic link.
Not having this symbolic link prevents lua-ev from finding the shared
version of the luajit library, and it fallbacks to using the
libluajit.a static library. However, this static library is not built
with -fPIC, so using it within a shared library doesn't work, and
leads to build failures on architectures that really do want to have
non-fPIC code into a shared library, such as x86-64.
By passing LDCONFIG=true during the installation steps of luajit, we
ensure that the symbolic links are created, which allows lua-ev to
detect the shared library properly, making everybody happy.
Investigation conducted with Samuel Martin. Thanks!
