Cross compilation problem

[xinyiman]

Hi guys, i have a problem. I install the 32 bit trunk version of lazarus/fpc on my pc. Run perfectly, but when use darwin cocoa cross compilation return this:

Why?

I don't do Mac but, I do know you need all the library files on your compiling PC for the target. It wants to link in  file that you
don't have in your paths, mainly the cocoa libraries I would say..

 By looking at it, it seems that you are using the "/" slashes where as in windows it's "\". I am not sure if the compiler is
smart enough to switch those for you ? But in any case, it looks like it maybe ignoring those files.

 Cross compiling is such a pain in many cases for many reasons..., oh well.

This?

This is a limitation of the FPC unzipper: your install-path is too long for the Darwin library to unpack.

But fpcupdeluxe not return error.

[xinyiman]

no suggestion?

[Soner]

Linker says it can't found cocoa framework:
ld: framework not found Cooa

I think, your cygwin environment doesn't contain cocoa and other apple frameworks.

Why don't you use macos in virtualbox?
Macos devolopment is stupid enough on native mac and you will get only errors with your cygwin environment.

In fact I'm trying to do the cross compilation from windows. If I install the 64-bit version of lazarus the cross compiler works, but there is a bug in the timestamptomsecs function. If I install the 32-bit version the cross compiler does not work.

[Cyrax]

To get  the timestamptomsecs function to work properly, you need to build native 64-bit compiler and its whole compiler suite.  Cross compiling from 64-bit to 32-bit will never work.

[xinyiman]

Look, I installed the cross compilers with fpcupdeluxe. And anyway the cross compilation from win64 to darwin64 (cocoa) does not work either. While from darwin64 to win64 or win32 it works properly.
