Reassembly since 3.91/3.90?

tinman · Post by **tinman** » Sat Oct 16, 2004 10:36 am

Is this the correct syntax to re-assemble a file:

pbcompiler /REASM

And nothing else because it uses the PureBasic.asm file? I've tried it with the name of the original source file too, but no luck. Either I'm being a chump or something's broken because I get nothing out of the compiler after "Creating executable", but the file "Compilers\Linker.out" contains the following:

Code: Select all

POLINK: error: Unresolved external symbol '_PB_InitSimpleList'.
POLINK: error: Unresolved external symbol '_PB_InitRequester'.
POLINK: error: Unresolved external symbol '_PB_MessageRequester2'.
POLINK: error: Unresolved external symbol '_PB_FreeSimpleLists'.
POLINK: fatal error: 4 unresolved external(s).

The original PB code was:

Code: Select all

MessageRequester("foo", "bar", #MB_OK)
End

And the generated assembly output was:

Code: Select all

True, seems like there is a problem, I will take a look.
