Thank you for your bug report. The error occurs on compilation of glpsql.c because str2int is declared in both glplib.h and in m_string.h, where the latter is included via mysql.h. (I'd like to note that mysql.h is a public api header, so it should keep the namespace clean, but it does not, having declared many non-reserved non-prefixed identifiers in secondary headers.) To fix the bug please add the #undef directive at the beginning of the file glpsql.c as follows: . . . #include "glpmpl.h" #include "glpsql.h" #undef str2int /* <--- this line should be added */ . . . This must work because str2int is not used in glpsql.c. This bug will be fixed in a next release of glpk. _______________________________________________ Bug-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-glpk
