#146535 - compiler warnings Responding to: ???'s previous message |
What happens if you don't mess with the code?
Does it build "as-is" ? Are these the only warnings you get, or are they preceded by any others? When the code is as is - I have to remove the reference to inttypes.h and redefine stuff like inline and uint8_t. After that, there would be a DATA segment too large C249 error in the CRC lookup table and what appears to be the receive buffer. Then it has trouble with the function pointers struggling with trying to put function parameters on the stack (or the lack of one, I should say). So no - it does not build out of the box. :-) Here's the complete log of compiler errors: Build target 'Target 1' assembling STARTUP.A51... compiling porttimer.c...
