[QUESTION] Compile error on ppc32 with compilation option '-fdata-sections'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,


When I was compiling the ppc32 kernel with the compilation option '-fdata-sections', a compilation error occurred and the message was as follows:


    "Inconsistent kallsyms data

    Try make KALLSYMS_EXTRA_PASS=1 as a workaround"


After comparing the symbol tables, I found that the "_end" and "__bss_stop" positions in Symtem.map and tmp_System.map are different: in Symtem.map they are in the middle of the symbol table. In tmp_System.map, they are at the end of the symbol table.


commit af73d78bd384aa9b add "strip-debug" to improve performance. However, the addition takes effect only for tmp_vmlinux but not for vmlinux. As a result, the symbol tables are different after the "-fdata-sections" compilation option is enabled.


How the "strip-debug" compilation option affects symbol table order?

Can "strip-debug" be added during vmlinux generation?


Kind regards,

Weihua
