[toshic]

Do you have libfcgi dev package installed?

[simmerlee]

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 !

[wangfengfly]

make clean solves the problem.

[JuergenKosel]

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.

[JuergenKosel]

I have found the cause of the problem:

libfcgi/examples/Makefile.am

Line 37 in f3cef74

echo_cpp_LDADD = $(LIBDIR)/libfcgi++.la

This line should become this:

echo_cpp_LDADD   = $(LIBDIR)/libfcgi++.la $(LIBDIR)/libfcgi.la

[toshic]

It is better to send these fixes to debian, this fork was made just to send changes to debian.

[JuergenKosel]

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?
