When you link your app to a shared library, it's required that library stays available whenever you run the app. A simple workaround to fix this is creating a symbolic link to libswift.so.1.2 called libswift.so. In these cases, g++ also cannot find the library file. Note 2: In some cases, the library file name is followed by its version, for instance libswift.so.1.2. Note 1: -l option gets the library name without lib and. In this case you should supply the g++ with the following options: g++ main.cpp -o main -L/home/taylor -lswift When g++ says cannot find -l, it means that g++ looked for the file lib in addition to default paths.Įxample: Assuming you have a library at /home/taylor/libswift.so, and you want to link your app to this library. So, to finally fix it so I could compile MySQL with my own version of ZLIB (rather than the bundled version): sudo ln -s /usr/lib/libz.so.1.2.8 /usr/lib/libzlib.so This is the output I got: =Īttempt to open /usr/x86_64-linux-gnu/lib64/libzlib.so failedĪttempt to open /usr/x86_64-linux-gnu/lib64/libzlib.a failedĪttempt to open /usr/local/lib64/libzlib.so failedĪttempt to open /usr/local/lib64/libzlib.a failedĪttempt to open /usr/lib64/libzlib.so failedĪttempt to open /usr/lib64/libzlib.a failedĪttempt to open /usr/x86_64-linux-gnu/lib/libzlib.so failedĪttempt to open /usr/x86_64-linux-gnu/lib/libzlib.a failedĪttempt to open /usr/local/lib/libzlib.so failedĪttempt to open /usr/local/lib/libzlib.a failedĪttempt to open /usr/lib/libzlib.so failedĪttempt to open /usr/lib/libzlib.a failed
#SERIAL NUMBER SIMPLY FORTRAN 2.28 HOW TO#
I thought to actually check the help text for the ld command: ld -helpįrom that, I figured out how to run ld in verbose mode (imagine that): ld -lzlib -verbose It added more confusion than anything else.
I came across another post on the Internets that suggested to run make with LD_DEBUG=all: LD_DEBUG=all makeĪlthough I got a TON of debugging output, it wasn't actually helpful. So, I thought, surely that couldn't be the problem. so file actually exists and if it doesn't, then create a symlink to the versioned file, for example, zlib.so.1.2.8. I did some Googl'ing and kept coming across different issues of the same kind where people would say to make sure the. I was receiving an error like this during compilation: /usr/bin/ld: cannot find -lzlib To figure out what the linker is looking for, run it in verbose mode.įor example, I encountered this issue while trying to compile MySQL with ZLIB support.
