wish of those help By default on non embedded Linux, you'll get dynamic linkage. If you want to change that, you can specify it in LDFLAGS; code :
LDFLAGS+= -Wl,--Bstatic -lmylib -Wl,--Bdynamic

 How to use static library(.a file) instead of a group of object files(.o) to create a shared library
By : user2377187

I think the issue was by ths following , Shared libraries libfoo.so should contain PIC code and static libraries libfoo.a contain ordinary non PIC code. So you cannot create a shared library from a static one. Shared libraries want Position Independent Code because their segment(s) is mmap(2)-ed at nearly arbitrary and variable addresses - without MAP_FIXED ... See also ASLR. code :
g++ -Wall -c -O foo.cc -fPIC -o foo.pic.o
g++ -Wall -c -O foo.cc -o foo.o
g++ -shared foo.pic.o bar.pic.o -ldep -o libfoobar.so
ar cv libfoobar.a foo.o bar.o

ld fails to link a static library to a dynamic library even when all files are compiled with fPIC

I wish this helpful for you The compiler used /opt/rh/devtoolset-4/root/usr/bin/c++ is other than /usr/bin/c++. If those two compilers have different versions of C++ headers they may produce libraries that have different symbols for methods (name mangling). There may be also other reasons why linking may fail if the compiler versions are different.
I would recommend compiling C++ code so that at least the major version of gcc is the same when compiling each C++ library.

 Static library having object files with same name containing static variables with same name

it should still fix some issue Global static variables have internal linkage, so there is no way for them to be treated as the same even if there is no difference in names, mangled or otherwise.
There will be no conflict.

 autoconf cannot link my object files - undefined reference to `Gtk::Main::Main (static library issue?)

hop of those help? Doh, I finally found the magic search terms which pointed me to the answer. Linker flags in wrong place shows that I am mis-using LDFLAGS and should instead use LDADD.
