SuitesParse installation fails about powsybl-math-native

[mathbagu]

It seems the file (SuiteSparse-5.4.0.tar.gz) you downloaded is not complete. Do you have an error before we try to extract the content?
Could you give us the checksum of your downloaded file?

[tarnh]

You were right with the partial download. But then something else emerged:

[ 72%] Built target suitesparse
make[2]: *** No rule to make target 'thirdparty/suitesparse/lib64/libklu.a', needed by '../target/classes/natives/linux_64/libmath.so'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:109: CMakeFiles/math.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

[mathbagu]

Is it possible to send us the complete log? I'm pretty sure you have a compilation error in SuiteSparse but without more information it's hard to give you a better answer.

About your download issue, we will add a test to check the download is complete before trying to extract the content of the archive.

[tarnh]

Where should the logfile be located? I can't find it inside ./build/thirdparty/suitesparse_source/SuiteSparse/

[mathbagu]

Simply copy/paste the content of the console into a file. Could you also give us the commands you type (options used).

[tarnh]

I'm doing a simple

mkdir build && cd build
cmake ..
make

and here's the log:

[mathbagu]

It seems the libklu.a is installed in -- Installing: /home/papa/aur/_power/powsybl-math-native/src/powsybl-math-native/build/thirdparty/suitesparse/lib/libklu.a (Line 1059 of your log file) whereas we are trying to find it in thirdparty/suitesparse/lib64/libklu.a

Could you give me your distribution name and the version of Cmake you use? Is it a 32bits or 64bits version?

As a workaround, you can fix the SUITE_SPARSE_LIB_DIR in the CMakeLists.txt at line 39.

I've just patched my CMakeLists → https://pastebin.com/F9xRUEVM

But then I've still got
make[2]: *** No rule to make target 'thirdparty/suitesparse/lib64/libklu.a', needed by '../target/classes/natives/linux_64/libmath.so'. Stop.
So probably the error lies beyond
set(SUITE_SPARSE_LIB_DIR ${THIRD_PARTY_DIR}/suitesparse/lib64)

[mathbagu]

Could you try to set the SUITE_SPARSE_LIB_DIR to ${THIRD_PARTY_DIR}/suitesparse/lib instead of ${THIRD_PARTY_DIR}/suitesparse/lib64.
