Re: [Help-glpk] Linking error in AIX 6.1 for glpk 4.47

[Reginald Beardsley]

Souvik,

Please send me  the console output from the compile and link using the AIX equivalent of "CC -v" on Solaris and the output from "nm -Ago libglpk.a" and "nm -Ago your_main.o".   You may need to check the man pages.  I'm on Solaris and don't recall the exact AIX options.

The error suggests name mangling was used for the library compile, but not the application.  There's a smaller chance that AIX is objecting to symbols starting with an underscore.  Those are often reserved for internal compiler symbols.  As I recall  AIX was a bit more strict than other systems about such things.

Have Fun!

Hi
I am trying to run a c++ program in IBM AIX 6.1, which is using glpk 4.47. The same program is running on SOLARIS, Linux and HP-UX platform. But when I am trying to run the program on AIX, compilation is successful but at the time of linking it is giveing the following error

 

ld: 0711-317 ERROR: Undefined symbol: ._glp_lpx_create_prob
ld: 0711-317 ERROR: Undefined symbol: ._glp_lpx_set_prob_name
ld: 0711-317 ERROR: Undefined symbol: ._glp_lpx_add_rows
ld: 0711-317 ERROR: Undefined symbol: ._glp_lpx_add_cols
ld: 0711-317 ERROR: Undefined symbol: ._glp_lpx_set_row_bnds
ld: 0711-317 ERROR: Undefined symbol: ._glp_lpx_set_col_name
....

 

I have included the library path of glpk and the libglpk.a library in link command.

 

Thanks & Regards,
