I haven't install libfcgi dev package. But now I installed libfcgi-dev package and it works well. So I don't use this libfcgi any more. Thank you very much !
Hello,
I have the same issue, that the symbol FCGX_InitRequest is missing for builds of shared library.
But if I call ./configure --disable-shared, then the build succeeds.
I have found the cause of the problem: https://github.com/toshic/libfcgi/blob/f3cef74607d4770c590c52fe9b9dd7c702149cd5/examples/Makefile.am#L37 This line should become this:
echo_cpp_LDADD = $(LIBDIR)/libfcgi++.la $(LIBDIR)/libfcgi.la
It is better to send these fixes to debian, this fork was made just to send changes to debian.
Hello @toshic according to https://packages.debian.org/buster/libfcgi-dev the upstream project seems to be https://github.com/FastCGI-Archives/fcgi2 (git tag 2.4.0 ) Do you agree?
