libcoinmumps.so.3: cannot open shared object file

[dvogureckiy99]

Hi, I try compile code Ipopt with make -j4 and get error, but I installed it already:

After I changed command ./../configure --with-mumps-cflags=-I/usr/local/include/coin-or/mumps/ --with-mumps-lflags=-l:

/usr/bin/ld: /home/dvogureckiy99/git/Ipopt/build/src/.libs/libipopt.so: undefined reference to `dmumps_c'
collect2: error: ld returned 1 exit status

And I also tried A precompiled MUMPS library provided by a distributions package manager. Installed package libmumps-seq-dev and use the configure flags --with-mumps-cflags=-I/usr/include/mumps_seq --with-mumps-lflags=-ldmumps_seq.

./../configure --with-mumps-cflags=-I/usr/include/mumps_seq --with-mumps-lflags=-ldmumps_seq

And I have got the same error.

In the first case, --with-mumps-lflags=-l is wrong. The argument --with-mumps-lflags expects all flags that are necessary to link against the Mumps library. I don't see what a single -l is supposed to achieve.
Easiest is usually to build Ipopt with the same --prefix as where you installed ThirdParty-Mumps before and let Ipopt's configure figure out the compiler and linker flags automatically.

I cannot really say why the second case fails with the same error. I see that this is something that worked for me once. Just check that the -ldumps_seq argument indeed made it into the linker flags (run make with V=1) and if that is the case, check whether libdumps_seq contains symbol dmumps_c, or whether there is another library that does so now.

Thank you for the answering me and your contribution.

I am nooby in all this instructions. Can you describe for me more deeply:

1. For checking that the -ldumps_seq argument indeed made it into the linker flags I should run make V=1 -j4 ?
2. And how to check whether  libdumps_seq contains symbol dmumps_c, or whether there is another library that does so now ?

[svigerske]

1. Yes.
2. I would use nm to list the symbols in the library.

[dvogureckiy99]

1. Yes.
2. I would use nm to list the symbols in the library.

Sorry, for my misunderstanding. for 2 would be correct: nm -dmumps_c libdumps_seq

I tried let Ipopt's configure figure out the compiler and linker flags automatically and get the same error. I run make V=1 -j4 after ./../configure and get:

make[3]: Entering directory '/home/dvogureckiy99/git/Ipopt/build/src/Apps/AmplSolver'

/usr/bin/ld: /home/dvogureckiy99/git/Ipopt/build/src/.libs/libipopt.so: undefined reference to `dmumps_c'
collect2: error: ld returned 1 exit status

And after ./../configure --prefix=/usr/local/ I get the same error.

[dvogureckiy99]

I reinstall MUMPS and then ./../configure -> make -j4 without everything else and this worked.

[dvogureckiy99]

but I encountered new error from make test:

You could add the path where you libcoinmumps.so.3 was installed to your LD_LIBRARY_PATH. Or just ignore it if you aren't going to use the Java interface.

[dvogureckiy99]

Thank you, Okey, I found this file there /usr/local/lib , and I added it by adding to .bashrc this line export LD_LIBRARY_PATH=/usr/local/lib. make test went right.
