I created a .so file and put it in the location /opt/lib and added this path to LD_LIBRARY_PATH now after this when I try to compile my main program with the following command:
g++ -Wall -I/home/alwin/Development/Calculator/ main.cpp -lcalc -o calculator I get the following error:
/usr/bin/ld: cannot find -lcalc collect2: ld returned 1 exit status Can someone help me with this. I created the shared library using the code blocks IDE

“/usr/bin/ld cannot find -lltdl” Error and Solution The “/usr/bin/ld cannot find -lltdl” error is related to the C development library named ltdl-dev . So installing the libtdl-dev can resolve this error.
LDFLAGS: Extra flags to give to compilers when they are supposed to invoke the linker, 'ld', such as -L. Libraries (-lfoo) should be added to the LDLIBS variable instead. LDLIBS: Library flags or names given to compilers when they are supposed to invoke the linker, 'ld'.
Add -L/opt/lib to your compiler parameters, this makes the compiler and linker search that path for libcalc.so in that folder.

When you make the call to gcc it should say
g++ -Wall -I/home/alwin/Development/Calculator/ -L/opt/lib main.cpp -lcalc -o calculator not -libcalc.so I have a similar problem with auto-generated makes.
You can create a soft link from your compile directory to the library directory. Then the library becomes "local".
cd /compile/directory ln -s /path/to/libcalc.so libcalc.so If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
