Hello,

I have a problem while trying to compile the zlib and libpng for a LPC11C24 : whenever I try to build the project, the compiler saids :
c:\nxp\lpcxpresso_4.2.3_292\lpcxpresso\tools\bin\../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/include/sys/types.h:4:32: error: no include path in which to search for sys/types.h

Have you got any idea of how to solve this ?

Thank you,
netsupra

I'm not sure about the specifics of your situation, but here are a few ideas that might help you find the problem...

Do you [I]#include "sys/types.h"[/I] in your code? If so, you can select that line in your code and press F3 (or right click->Open Declaration). That should open the actual file up. From there, you should see the location of the file and make sure that it is in your include paths for that project (Make sure you have the project selected, click "Quick Settings" button on the toolbar then select "Include paths")

Also, it could have something to do with using REDLIB vs NEWLIB. Look that up under your project defines (Make sure you have the project selected, click "Quick Settings" button on the toolbar then select "Defined Symbols"). You might have to read about differences between REDLIB and NEWLIB in other areas for help.

Usually sys/types.h is referring to host's environment (eg. in Linux, FreeBSD or Win32), and I don't think CodeRed GCC toolchain library has it (no sys/types.h in CodeRed / Newlib libc headers)

I think you need to configure the zlib and libpng source code to not use the OS dependent files (including using autoconf to configure it as cross-compilation).

sys/types.h is provided for newlib.

Just switch your library to newlib and you can use it.

See

and using Newlib (Nohost) or Newlib(Semihost)

Thank you for your help.
I've switched to newlib and it is working.
Further, Newlib uses more memory than Redlib for the same source code.
