GNU Octave interface

Open 1a7r0ch3 opened this issue 5 years ago • 4 comments

Here is a install_octave.m script, a slight modification of the src/general.h header and of the documentation in README.md enabling interface with GNU Octave. So that Matlab aficionados can go free and open-source!

Thanks a lot for this nice contribution. I myself am finding it increasingly harder to gain access to a Matlab license to test new versions of proxTV, so an Octave interface is welcomed.

However I have been unable to reproduce the installation with success. When running install_octave.m I would get a "multiple definitions of mexFunction" for each one of the Matlab .cpp files being compiled. Which is silly, because the error claims about a function with equal name being defined in the same line.

Here is the full error log (though for some weird reason some of the prints are in spanish?)

proxTV successfully installed.

Any idea where this problem could come from?

Hi,

Consider the following fact :

Since you provide many solvers that you compile individually into objects files (.o), the mex command line issued gives the dependencies as ".o" to avoid listing all of them ; as in eval(['mex -v -lblas -llapack -lm ' solver{:} '.cpp "*.o"']); The trouble is that some versions of Octave (I think 4.x or less) also create an intermediate object file for the final mex binary, and do not delete it automatically. So, once the first solver ("solveTV1_condat" in the current list) has been compiled, the corresponding object file is still there, containing a mexFunction() entry. Then, when the next solver ("solveTV1_condattautstring") is compiled, the former object file get listed as dependency (through the "*.o"), and the two mexFunction() entry conflicts.

I am sure that the problem revolves around the above explanation, because when adding the linker flag "-z muldefs" (basically allowing multiple definitions; see the documentation of ld), the problem disappears. I submitted a commit correspondingly.

However, the above explanation is certainly incomplete, because:

  1. the very first in the list, solveTV1_condat, already gave the "multiple definition" error; and
  2. I actually already took care of the multiple definition problem, with the line `system(['rm -f ' solver{:} '.o']); so that the faulty object files should not exist in the system when the next solver is compiled. Note that if you do force the linkage with -z muldefs but do not remove the object files after each compilation, the actual problem arise : all solvers will use the mexFunction() of solveTV1_condat as their entry!

To sum up, the workaround is to add the -z muldefs compilation flag, and double check that the object files are deleted after each compilation to avoid actual multiple definitions of the mexFuntion. This does not seem to be necessary with Octave 5. Note also that I only tested solveTVgen, so you might wanna check that the other solvers compile correctly.

By the way, if you want to avoid the Spanish output of gcc (which is most certainly the C compiler called by mex), start Octave with the LANG environment variable set to C (or an English locale). On my shell configuration file, I actually have alias octave='LANG=C; /usr/bin/octave-cli' # LANG is for gcc messages.

Cheers

Thanks a lot for this nice contribution. I myself am finding it increasingly harder to gain access to a Matlab license to test new versions of proxTV, so an Octave interface is welcomed.

However I have been unable to reproduce the installation with success. When running install_octave.m I would get a "multiple definitions of mexFunction" for each one of the Matlab .cpp files being compiled. Which is silly, because the error claims about a function with equal name being defined in the same line.

Here is the full error log (though for some weird reason some of the prints are in spanish?)

Thanks for the LANG tip!

However I'm afraid that even after the update the error persists. I have made sure there are no .o files lying around in the project, but still the log I get now is

Hi,

With a closer look, I understand that octave compiles mex files in two steps : first create an object file, and only then create the executable file from this object. Since the second step contains both "*.o" and "solveTV1_condat.o", the latter appear twice, hence the multiple definitions (and this finally explains the points 1) and 2) that I raised in my previous message). Moreover, it can be seen from your log files that, with your version of octave or gcc, the option -z muldefs is passed for the first step, but not for the second step :

 g++ -c [...] -fPIC -DOCTAVE -z muldefs -O3 -fopenmp

solveTV1_condat.cpp -o solveTV1_condat.o g++ -shared -Wl,-Bsymbolic -o solveTV1_condat.mex *.o solveTV1_condat.o [...]

In this case it is not possible to resort to the "*.o" to specify dependencies, they must be listed explicitely !

My last commit should do it.

Thanks for the LANG tip!

However I'm afraid that even after the update the error persists. I have made sure there are no .o files lying around in the project, but still the log I get now is [...]
