How to compile planet?

[edwardxu0]

I am having trouble compiling planet on Linux.

Could you provide a makefile?

If not, which lp slove library are you using?
Could you point me the link?

[bunelr]

What problems do you encounter?

The following worked for me (copy pasted from the instructions in my repository

cd planet/src
# sudo apt install valgrind qt5-qmake libglpk-dev # if necessary 
qmake
make
# if you encounter linker issues, move -lsuitesparseconfig to the end of the flag list

(the last comment is because I was sometimes seeing some linker error. Moving the flag "-lsuitesparseconfig" to the end of the list in the src/Tool.pro file solved it (after rerunning the makefile generation)

[edwardxu0]

Thank you so much for the quick response, Rudy.

On Ubuntu 18.04
When it says,
/usr/bin/x86_64-linux-gnu-ld: cannot find -lltdl'.
install the missing library, libltdl-dev.

On Ubuntu 16.04,
Move -lsuitesparseconfig to the end of the flag list when you have some linker issues.

[bunelr]

Have you tried installing the library that seems to be missing? (libltdl-dev)

Hi @edwardxu0 and @bunelr.

Sorry for forgetting to add the command to actually build the tool to the README file. It has not been added. The "libltdl-dev" package was indeed an additional dependency that is now also listed as such in the README file. That package is needed by the GNU linear programming toolkit, and it's a bit weird that it is not listed as a dependency of it in the package manager (perhaps because it is only needed for static builds).

I got the error

collect2: error: ld returned 1 exit status
Makefile:167: recipe for target 'planet' failed
make: *** [planet] Error 1

when I typed make in terminal

Hi @tianshubao1 - Could you copy&paste a bit more of the error messages that you get? The "ld returned 1 exit status" line informs you that a linker error happened earlier. Seeing the actual linker error would be helpful.

Also, could you add which type of system you are using (type of Linux, Mac, etc.)? For compilation/linking errors, this information is typically helpful.

[tianshubao1]

Thanks for the prompt reply. I am using ubuntu 16.04, Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz.

I typed make in src directory.

I unfortunately do not have access to a Ubuntu 16.04 machine (any more).

Could you try running the following command (in the "src" folder)?

g++ -m64 -Wl,-O1 -o planet Options.o Solver.o System.o main.o verifierContext.o supersetdatabase.o -static -lglpk -lgmp -lumfpack -lcholmod -lamd -lcolamd -lccolamd -lcamd -lsuitesparseconfig -lz -lltdl -ldl

It's the same as the one that did not work, except that the order of the libraries is now different.

[tianshubao1]

It seems it works now. I got an extra file in the folder after tying the command you gave me.

Then I type make again. It said nothing to make.

[progirep]

The extra file should be the executable (if "make" says that there is nothing to make).

I do not know why Ubuntu 16.04 vs. Ubuntu 18.04 makes a difference here. Either the way linking works has slightly changed, or it is because of a change in the GLPK libraries.

I'm closing this issue for now. Please let me/us know if you have further questions.
