Re: [Help-gsl] Hello All, didn't find any tips for BorlandC++ Builder v6 and GSL lib

[Denis Glehen]

Hello Joseph and John and thanks for answering.

I tried to begin translating on CPPBuilder6 but i had several errors during
compiling. And as
i'm not aware with linux makefile system, i don't know how to rebuild .lib
files using builder.

I tried to use it on QT and it works very well. in fact static lib (.a)
formats are compatible so that it's very easy. The fact is that all my code
has been done on borland. i'm searching for solutions but i think that it
will be hard to find.

Visual Studio is not compatible with BCC, agree ? seem that lib formats are
not the same.

best
