I just tried to install apache 2.4.25 with these configure parameters
./configure --prefix=/opt/apache2/ --with-apr=/opt/apr --with-apr-util=/opt/apr-util --with-pcre=/opt/pcre --enable-ssl --with-ssl=/usr/local/ssl
and seems no problem. But when I tried to make, it halted and says
/usr/bin/ld: cannot find -lcrypt
Then I tried to find out whether libcrypt* library is loaded, and yes is there
[root#localhost httpd-2.4.25]# ldconfig -p | grep libcrypt
libcryptui.so.0 (libc6,x86-64) => /usr/lib64/libcryptui.so.0
libcryptsetup.so.1 (libc6,x86-64) => /lib64/libcryptsetup.so.1

libcrypt.so.1 (libc6,x86-64, OS ABI: Linux 2.6.18) => /usr/lib64/libcrypt.so.1
Any clue about this?

I'm using CMake 3.21.3 - from Kitware's download page (binary distribution). I've noticed that:
$ ldd `which cmake`

/lib64/ld-linux-x86-64.so.2 (0x00007fdc4a8d3000)
contains references to two unexpected libraries. One is librt, which is probably explained by its use within cmlibuv (which CMake in turn uses); but the other, which I can't explain, is libgtk3-nocsd. Why would the CMake binary (not cmake-gui mind you) use this library?
It's not linked against libgtk3-nocsd. Something in your environment has set LD_PRELOAD to add libgtk3-nocsd. Try running ldd again with LD_PRELOAD unset.

In my project, i use singularity to build a mpi.sif.
I have a openMPI in my host file system. I do not want to install mpi in the container.
so i try to copy the mpi files to container.
Some content of the define mpi.def is like :
[stack#node01 pitzDaily]$ cat mpi.def
Bootstrap: docker
From: centos:7
%help
This recipe provides an OpenFOAM-7 environment installed
with GCC and OpenMPI-4.
%labels
Author stack
%files from stage_name
/share/apps/openmpi/intel/3.1.2/ /opt/openmpi-3.1.2
%post
### Install prerequisites
I can get the mpi.sif successfully after the building.
But i ran mpicc in container, it is wrong:
Singularity> mpicc
mpicc: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No
such file or directory

Who can give me a help?
I have a Makefile-based project that needs to link against the BLAS linear algebra library. There are a huge number of different versions of this library, so trying to find it using make rules would be painful, to say the least. Luckily cmake has a FindBLAS.cmake module that should make it easier. Except that I can't get it to work.
On CentOS7 with both blas-devel and openblas-devel installed via yum, I can do
> ldconfig -p | grep blas
libopenblas64_.so.0 (libc6,x86-64) => /lib64/libopenblas64_.so.0

libblas.so (libc6,x86-64) => /lib64/libblas.so
so both libblas.so and libopenblas.so are in default library paths. And, if I simply give -lblas or -lopenblas to my linker, everything works fine. But, when I try to use cmake to find it automatically, I get
> cmake3 --find-package -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=EXIST -DNAME=BLAS
BLAS not found.
CMake Error: Problem processing arguments. Aborting.
cmake is version 3.12, and the same command works for other packages (Java, Boost, Git, etc). FindBLAS.cmake is where I would expect it at /usr/share/cmake3/Modules/FindBLAS.cmake.
What am I doing wrong???
I have a linking problem which I cannot explain. The program contains references to FFTW functions in a file called fft.cpp. The linking command is as follows (I skipped the rest of object files):
/usr/bin/g++ common/CleanerND.cpp.2.o ... common/fft.cpp.2.o
-o cleaner3d -Wl,-Bstatic -Wl,-Bdynamic -lmkl_intel_lp64 -lmkl_sequential -lmkl_core
-lfftw3f -lgsl -lgslcblas -lm -lglib-2.0 -lz -lm -lpthread -fopenmp
The superfluous -Wl,-Bstatic -Wl,-Bdynamic options are generated by Waf, which I use as the build system. I use the default toolchain that comes with Ubuntu 12.04: GCC 4.6.3, binutils 2.22.
The problem is that the linker does not detect and resolve the references to the FFTW functions. When run, the program aborts with this message:
cleaner3d: symbol lookup error: cleaner3d: undefined symbol: fftwf_malloc
The output ofldd shows that FFTW is not being linked at all:
$ ldd cleaner3d

/lib64/ld-linux-x86-64.so.2 (0x00007f6f169b2000)
This is clearly the linker's fault, since the output of nm shows that it contains references to FFTW:
$ nm build/common/fft.cpp.2.o | grep fftw
U fftwf_destroy_plan
U fftwf_execute_dft
U fftwf_free
U fftwf_malloc
U fftwf_plan_dft_1d
U fftwf_plan_many_dft
I found out that this might be somehow related to the linker option --as-needed, which is passed by default since Ubuntu 12.04 - and indeed, when I add -Wl,--no-as-needed to the command line, the problem disappears. However, this workaround should not be necessary. I don't understand why the linker won't properly link FFTW with --as-needed enabled. Can anyone shine some light on this? Is this a linker bug? Why only the FFTW library is affected?
I'm having a weird linking problem and am only beginning programming with c++ so I'm not terribly sure what it means...

Resolution
Partially resolved thusly, I linked to the shared libraries in the /usr/lib folder, I'm not sure why g++ wouldn't look in there, but it just wouldn't.
Useful links here and here
It's rather simple.
The OS looks for libraries in the directories that exist in the ldconfig.
it seems that libOgreTerrain.so links against some other libraries that were not explicitly specified.
Try this first:
LD_LIBRARY_PATH=/home/esr/ogre/lib ./a.out
You can display dynamic linking paths like that:
ldd ./a.out
