I completely agree with this. In my case, as far as I could tell, the installer (RPM) was supposed to set a link, for that particular library. That is not always the case, however.

You should definitely try to install the -dev or -devel package if possible.

Hi everyone
I have a similar error

/usr/local/arm7/lib/gcc/arm-elf/4.1.1/../../../../arm-elf/bin/ld: cannot find -lc
collect2: ld returned 1 exit status
make[1]: *** [test-sram] Error 1


I am new one programming on linux, so can you help me to fix this error?
Do "-lc" is a library??

Thanks

trying to give make command to our project. But when we are giving make command in ubuntu it gives an error that saying
/usr/bin/ld: cannot find -lmysqld
But installed mysql in ubuntu and all necessary headers.

Ubuntu "lmysqld = libmysqld.a" is provided by the package 'libmysqld-dev'.

sudo apt-get install libmysqld-dev

the compiler was looking for "libclntsh.so" and we have libclntsh.so.11.1, i just created sym link libclntsh.so pointing to libclntsh.so.11.1 and added PATH variable with location of that .so file and it found the lnctsh symbol and it compile without error.

See post #19 : Please do not ask off topic questions in another members ( old ) thread.

lclntsh = libclntsh.so ( Or libclntsh.a ).

libclntsh.so : Suggest : Make a symlink to libclntsh.so.XX
( libclntsh.so.XX is part of "Oracle-runtime" or similar.
