symbian rodata overlap errors

error description:

arm-none-symbianelf-ld: C:/proj/group/Proj_Data/GCCE_UREL/Proj.exe: section .data lma 0x400000 overlaps
previous sections

 

查詢網上資料:

Your code size (.rodata) is too large so it overlaps the hard coded .data section begining at 0x400000.

I've changed these hard coded .data section in /epoc32/tools/cl_bpabi.pm line 793 & 799 :

"/$(CODE_SEGMENT_START) ", "/$(DATA_SEGMENT_START) 0x400000 ", "/$(SYMVER_OPTION) ","/$(SO_NAME_OPTION) ","$LinkAs"

I replaced 0x400000 by 0xA00000 and I get my app properly linked linked, and it works fine on phone.

 

我改了以後好像沒什麼用，看到這個：For UREL static solution everything is fine as the size is much more less then 4mb, but for UDEB (to be able to debug on hardware) the size goes beyond...

和我情況一樣，我也是編譯gcce udeb才不成功

然後我改MMP檔案：

EPOCSTACKSIZE                           0x10000
EPOCHEAPSIZE                             0x100000 0x4000000

變為

EPOCSTACKSIZE                           0x100000
EPOCHEAPSIZE                             0x100000 0x4000000

再編譯，搞定
