Hi!
Quick question. I tried to modify the printk trace generator to print
the output traces into a text file instead of the console. On running
the normal link and trace linker commands there are no compilation
errors. However when I run the application executable using GDB it
says [Inferior 1 (process 42000) exited normally].
This is what I am doing to the code section of the rtld-print.ini's
printk generator:
static inline void rtld_pg_printk_entry(const char* func_name,
void* func_addr)
{
FILE* fp = fopen("trace.txt", "a");
Always check the return value of functions which may fail.
fprintf (fp, ">>> %s (0x%08x)\n", func_name, func_addr);
fclose(fp);
}
Is there something wrong with this approach?
Maybe the wrong execution context. The fprintf() must be called from
task context. I would debug the rtld_pg_printk_entry() function to
figure out what is going on.
