[Qemu-devel] Unable to Run Gprof Successfully on QEMU
I'd appreciate any input on how to run gprof successfully on qemu. I'm new to gprof and am probably missing some steps. I successfully ran gprof on a sorting program available online, then I attempted to run gprof on qemu. Here are the steps I take: I'm trying to run gprof on qemu, but am unsuccessful. my os is linux, my qemu version is 0.8.2. I configure qemu with the options configure --prefix=/install_path --enable-gprof. Then I make and make install. I run qemu successfully using the options /install_path/qemu -hda diskimage.img -m 256 which results in the gmon.out file. My run of qemu involved starting the image (virtual linux OS), running a few simple commands and shutting the image down. Finally, I run gprof /intsall_path/qemu gmon.out result.txt which gives the error: gprof: file 'qemu' has no symbols' Are there any other configuration options required? Should the image be run with differently? thank you, atoosaah

A way to get the debug symbol is to fetch the source and recompile it... -- J. Mayer [EMAIL PROTECTED] Never organized

How do I enable debugging? I checked the configure file and I do not see any options for compiling with debugging, i.e. there is no --enable-debug option. I see that the default parameters section of the configure file sets: gdbstub=yes but other than that i do not see any other reference to debugging. Also, I am working with qemu source code, which I configure, make, make install before every run. Thank you again. On 10/12/07, J.

That was it. I got it to work! Thanks so much for your help :-) On 10/12/07, Ben Taylor [EMAIL PROTECTED] wrote: Atoosaah S [EMAIL PROTECTED] wrote: How do I enable debugging?
