Hi, all I want to use LLVM to output a ELF object file as a library that can't be linked into IAR/Keil project. And the ELF file should include the debug information (eg. line numbers and symbol tables) that can't be read and processed in IAR/Keil IDE. How can I do it? Thanks a lot. ------------- Q.W ***************************** Legal Disclaimer ***************************** "This email may contain confidential and privileged material for the sole use of the intended recipient.
