 The target device OS is Brew MP, something like eCos, but it is much

And this supports shared libraries ?

I think the better choice would be to create a Platform/BrewMP.cmake which has 
all the right stuff, and use 
set(CMAKE_SYSTEM_NAME BrewMP)
in your toolchain file.

Are you sure you need this ?
This is in general a bad idea.

 
 SET (CMAKE_SYSTEM_NAME Generic)

Generic operating system does not support shared libs.
Do you have an operation system on your target device ?

[CMake] Doesn't support SHARED libraries during cross compiling using ARM RVCT40.

Re: [CMake] Doesn't support SHARED libraries during cross compiling using ARM RVCT40.

2011-06-14 Thread jianhua 
The background of this question is that I want to build one BrewMP project, the 
compiler is ARM RVCT40. 

Original build method is below:
1.  Build many static libraries.
2.  Link them to elf.
3.  Create mod file, final one.

Now What I need to do is to achieve these steps by CMAKE, any idea or support? 
Thanks.

TARGET myapp.elf
C:\progra~1\ARM\RVCT\Programs\4.0\650\win_32-pentium\armlink -o myapp.elf 
--vfemode=off  --split --reloc  --ro_base 0 --entry AEEMod_Load 
.\NavObj\AEEAppGen.o .\NavObj\AEEModGen.o .\NavObj\TeleNavAppUi.o 
.\NavObj\cpl.l .\NavObj\cis.l .\NavObj\cpf_ui.l .\NavObj\cpf_lbs.l 
.\NavObj\myapp.l --first AEEMod_Load
---
TARGET myapp.mod
.\elf2mod  myapp.elf  -output myapp.mod
elf2mod: RelocMod ro-base=0x200  rw-base=0x126040
elf2mod: Created myapp.mod
