Hello

We're trying to compile a lib done on CW ( apple linker ) on PB and we get a
lot of link errors :
___cvt_fp2unsigned
___save_fpr_24
___restore_fpr_24
___save_fpr_28
___restore_fpr_28
___save_fpr_21
___restore_fpr_21
___save_fpr_27
___restore_fpr_27
___div2i
___files
___cvt_dbl_usll

Any idea what we need to link ?
thank you
patrice.

I believe tthis is the same for you, but it may just be that you are
missing the crt1.0 library entirely.

Q. When I builde my program with CW7 to a Mach-o console binary. It
compiles fine but then has these link errors...

Link Error: ___save_fpr_26 is undefined
Link Error: ___restore_fpr_26 is undefined
Link Error: ___save_fpr_28 is undefined
Link Error: ___restore_fpr_28 is undefined

A. This is a known problem that pops up quite often. To fix it you need
to change your linking order to put the crt1.o library before (or
after?) the other libraries are included.

no that didn't work, i remember having this problem with __div3i but here
it's __div2i ( there's a slight difference between the names )

i have really no clue. ( is there a Project Builder newsgroup anywhere ? )

Thank you

I can tell you it definitely is the runtime library. And I can tell you
that Apple is a single pass compiler and linker so the link order makes
a big difference, I still think that this is a missing or more likely
out of order runtime library, which one I don't know.

fyi:

linking

crt1.o
libSystem.dylib
libstdc++.a

did the trick apparently ! ( i can't make functionnal exes on PB for some
reason but the built went just fine! )
