several linker errors

Demonio,

thanks for your response!

At first, I was also quite surprised, when I saw SYS_FreeString to be referenced rather than _SYS_FreeString. Then, however, I found a bunch of other functions which were also referenced without a leading underscore (e.g., PB_Blue, PB_Green, PB_Red) without causing any linker errors.

I am also afraid that I ran across a PB bug although I do net yet see how I can isolate it...

Is it possible to modify the assembler listing and continue from that (i.e. running the assembler and linker)?

That would proove our ideas - or not.

well, you could try changing all the SYS_FreeString's to the underscored version and use the reassemble command line option (/REASM on windows - unsure about OS X)

Demonio,

thanks for the hint - unfortunately, I can't see how to reassemble under MacOS X (--reasm does not work and --help does not mention reassembly)

Even inspecting the "PureBasic" program folder did not help further...

Does anybody else know how to "reassemble" under Mac OS X?

perhaps this means mac os x pbcompiler can't reassemble yet...

I looked at the pbcompiler -h screen too, and I can't see it either...

Ok, I found the origin of the linker errors

Today, I had some time to isolate the problem using a binary division approach (plus some heuristics

.

And I found that the FTP-related functions are the reason for the undefined external SYS_FreeString - without FTP functions, everything compiles and links fine.

What I haven't done, however, is to check the situation the other way round: will the error occur when I use FTP-related functions *only* (i.e. without the bunch of other functions I am using)

At least, I have a part of my system running now (sigh)

Ok,

I just tried to run the FTP example which comes with PB - and I got the same error!

Now it's time to submit a bug report...

Thanks for all your help!
