how to compile the test files of m4ri?

[סיאנג היונג]

Currently, I want to use the package 'm4ri' to solve system of linear equations. I installed the package on my linux server following the instruction on your website.

Then, I tried to compile the test_solve.c with the following command line:

gcc -std=gnu99 -lm -lm4ri -I/home/qarma/m4ri -O0 /home/qarma/m4ri/tests/test_solve.c

I could compile successful. But the problem is when I run with ./a.out, it returns segmentation fault.

As all the test files passed the 'make check' phase on my side, there should be no error in it. I think it should be the problem of flag.

Besides, I also installed it on my ubuntu with the following steps:

‌

git clone https://[e-mail]/senyang_haifa/m4ri.git
cd m4ri/
autoreconf --install
./configure
make
make check

And I compile the 'test_solve.c' with the following command line:

‌

gcc -lm4ri -lm -I /home/senyanghuang/m4ri tests/test_solve.c

This time I can not compile but it returns the following errors:

Would you please show me where the problem is?

Thank you!

To compile the tests, run make check.

Manual compilation works here, too:

‌

gcc -I. tests/test_solve.c -lm -lm4ri -L.libs/ -o foo
LD_LIBRARY_PATH="../.libs" ./foo

cannot reproduce.

still I got the same segfault.

On my ubuntu, it shows the following error when I compile

gcc -I. tests/test_solve.c -lm -lm4ri -L.libs/ -o foo
/usr/bin/ld: .libs//libm4ri.so: undefined reference to log2' /usr/bin/ld: .libs//libm4ri.so: undefined reference toround'
collect2: error: ld returned 1 exit status
