I am trying to configure apache using the following command:
./configure --prefix=/opt/nms/app/apache --with-apr=/home/kvanapal/httpd-2.4.20/srclib/apr --with-apr-util=/home/kvanapal/httpd-2.4.20/srclib/apr-util/apu--config --enable-mods-shared=all --with-ldap --with-included-apr --with-included-apr-util --enable-ldap
After this I am running the make command and this gives the following error towards the end:

Im using Cudas cuFFT library and therefore I have added the library path to $LD_LIBRARY_PATH. When compiling, Im using the -lcufft flag, after including the header with #include<cufft.h>. But I still receive the following errors:

Am I missing something crucial?

But gzip has been installed by default and is already the newest version. The makefile is generated by cmake. Any ideas what's going wrong?
Tried to install gzip and no change was made.
gzip is already the newest version (1.10-4ubuntu4.1).
The following packages were automatically installed and are no longer required:
libflashrom1 libftdi1-2
Use 'sudo apt autoremove' to remove them.

The error stays the same when running "make install".
I have a c++ program, which uses the FFTW3 library, which I would like to translate to Fortran. I am using Ubuntu 22.04.1.
I installed the FFTW3 library as detailed in Installation on UNIX
The c++ main program is named ksbenchmark.cpp and, using g++, I compile it and link it (to the math and fftw3 libraries) with
g++ -o my_executable.out ksbenchmark.cpp -lm -lfftw3
which works great.
I have translate the c++ code in Fortran, the source file being named ksbenchmrk.f90.
If I issue
gfortran ksbenchmark.f90 -lfftw3 -lm
I get error messages
/usr/bin/ld: /tmp/cca2xMGa.o: in function `ksintegrate_':
ksbenchmark.f90:(.text+0x59): undefined reference to `dfftw_plan_dft_1d_'

/usr/bin/ld: ksbenchmark.f90:(.text+0xa1c): undefined reference to `dfftw_execute_'
collect2: error: ld returned 1 exit status
I have spent the afternoon reading about it, and it seems I may have to use -I and -L flags such as
gfortran test.f90 -L/new/path/to/lib -I/new/path/to/include -lfftw3 -lm
as illustrated in the post Problems linking FFTW with gfortran (symbol(s) not found for architecture x86_64).
The first question is, what paths to use?
I can find files referring to fftw3 in /usr/local/lib as well as in /usr/local/include, but the attempt
gfortran ksbenchmark.f90 -L/usr/local/lib -I/usr/local/include -lfftw3 -lm
returns the same error as before

I am unable to understand which paths to the library are to be used.
How to find where the library is saved?
Why does not g++ need any paths to the library?
I apologise for how trivial the question might seem, I am a total newbie can ensure I put a significant effort in trying to sort this out. Any hint would be most appreciated, thanks
EDIT
Following Vladimir F Героям слава's advice, I tried using the nm command to verify the library contains what is expected to.
In /usr/local/lib
I found libfftw3.a and libfftw3.la files.
Issuing nm libfftw3.a I get quite a long list.
I tried looking for one of the commands I get an error about, dfftw_plan_dft_1d
nm -S libfftw3.a | grep dfftw_plan_dft_1d
and indeed it returns hits

Does anyone can help? Any reply will be highly appreciated!!
Thanks!
It is because the geant4.sh script in the Geant4 bin has not been run. This sets up the LD_LIBRARY_PATH variable which then allows these libraries to be found. (Note that you will need the data from CERN in order to successfully run geant4.sh)
I am trying to cross-compile ROS2 for Arm. The steps I am following can be found in here: https://github.com/ros2-for-arm/ros2/wiki/ROS2-on-arm-architecture
The build command used is
colcon build --symlink-install --cmake-force-configure --cmake-args -DCMAKE_TOOLCHAIN_FILE=aarch64_toolchainfile.cmake -DTHIRDPARTY=ON -DBUILD_TESTING:BOOL=OFF
The poco library cannot be found, however it is in "/work/ROS2_Bouncy/ros2_ws/install/poco_vendor/lib/libPocoFoundation.so.50" and it is correctly cross-compiled:
/work/ROS2_Bouncy/ros2_ws/install/poco_vendor/lib/libPocoFoundation.so.50: ELF 64-bit LSB shared object, ARM aarch64, version 1 (GNU/Linux), dynamically linked, BuildID[sha1]=6ba44c72e2162ca056b0dbde681dd4a8b5da5e35, not stripped
I wonder where I can modify the CMake script to specify the path to the thirdparty libraries. I tried to specify manually the path to Poco but it did not work:
add_library(Poco_import SHARED IMPORTED)
set_target_properties(Poco_import PROPERTIES
IMPORTED_LOCATION "/work/ROS2_Bouncy/ros2_ws/install/poco_vendor/lib/libPocoFoundation.so.50"
)
I also tried adding the path to the Poco library in CMAKE_EXE_LINKER_FLAGS
(-L) but no success.
Everything look to be compiled correctly, but I got an error at the linking stage:

Thanks to Tsyvarev who pointed to me the correct flag.
I added the following to the toolchain file and it solved the issue.
set(PATH_POCO_LIB "${CMAKE_CURRENT_LIST_DIR}/build/poco_vendor/poco_external_project_install/lib/")
set(PATH_YAML_LIB "${CMAKE_CURRENT_LIST_DIR}/build/libyaml_vendor/libyaml_install/lib/")
set(CMAKE_BUILD_RPATH "${PATH_POCO_LIB};${PATH_YAML_LIB}")
