log4cpp: Linux can't find the lib files

Question

I download the log4cpp in my Linux and I use the commands below to install:

./configure
make
make check
make install

After that, I can find the lib files below in the path "/usr/local/lib":

liblog4cpp.a
liblog4cpp.la
liblog4cpp.so
liblog4cpp.so.4
liblog4cpp.so.4.0.0

Then I tried to use the log4cpp in my cpp project, which is complied by gcc11.

But I got the error message:

Undefined reference to "log4cpp::Category::shutdown()"

I think it can't find the lib files. So I added liblog4cpp.so manually.

Now I got this error:

undefined reference to "pthread_key_create"

What should I do?

Answer 1

log4cpp is C++ lib, I recommend configure and build it using the same C++ compiler
