Hi all,



I met some trouble when I build oprofile. It shows me "kernel supports
perf_events... no¡°.



I have tried oprofile-1.0.0, oprofile-1.1.0, oprofile-0.9.6.



My building environment is kernel3.3.8, binutils-2.26 and popt-1.14.



I enclosed building log. Any help would be appreciated.



BestRegards,

Ryan

Hi Ryan,

The real problem seems to be:

checking for cplus_demangle in -liberty... no
configure: error: liberty library not found

The configure can't find the needed file ( libiberty.a) to build things with liberty. On fedora these are supplied by binutils-devel. I am not so sure what supplies them for the cross compile enviroment you are using.

Hi Will,

Thank you for your reply.

The building issue (" liberty library not found") was fixed. But the new issue("/usr/lib/libbfd.so : error adding symbols:") was appeared in oProfile-v1.0.0.

I don`t konw why it did not use my libbfd.so that I have given in configure parameter. And I am sure my libbfd.so( "/home/ryan/workdir/brcm/tvos2.0-dth/tvos-dbs/platform/linux_h5/target/external/binutils/usr/lib/libbfd.so ") is fine . Below is my building parameter:

export AS=$(TARGET_AS); \
export LD=$(TARGET_LD); \
export CC=$(TARGET_CC); \
export CXX=$(TARGET_CXX); \
export AR=$(TARGET_AR); \
export NM=$(TARGET_NM); \
export STRIP=$(TARGET_STRIP); \
export OBJCOPY=$(TARGET_OBJCOPY); \
export OBJDUMP=$(TARGET_OBJDUMP); \
export RANLIB=$(TARGET_RANLIB); \
export CFLAGS="$(CFLAGS) -I$(OUTDIR)/include ";\
export LDFLAGS="$(LDFLAGS) -L$(OUTDIR)/external/popt/usr/lib -L$(OUTDIR)/external/binutils/usr/lib"; \
export LD_LIBRARY_PATH="$(OUTDIR)/external/binutils/usr/lib:$(OUTDIR)/external/zlib/usr/lib:$(OUTDIR)/external/popt/usr/lib";\
export LIBRARY_PATH="$(OUTDIR)/external/binutils/usr/lib:$(OUTDIR)/external/zlib/usr/lib:$(OUTDIR)/external/popt/usr/lib";\
export ac_cv_va_copy=yes; \
./configure --host=mipsel-linux-gnu --with-kernel=/home/ryan/workdir/platform/linux_h5/platform/kernel/linux --with-extra-libs=$(OUTDIR)/external/popt/usr/lib/:$(OUTDIR)/external/zlib/usr/lib:$(OUTDIR)/external/binutils/usr/lib --with-extra-includes=$(OUTDIR)/include --with-binutils=$(PRIVATE_LOCAL_PATH)/../binutils/binutils-2.26 --prefix=$(TARGET_PREFIX) ;

I also build oProfile-v1.1.0 in the same configure parameter. The error message("kernel supports perf_events... no ") appeared again.

I have already opened the kernel option in ordering to make Linux support to oProfile.
CONFIG_PERF_EVENTS=y
CONFIG_PROFILING=y
CONFIG_OPROFILE=y
CONFIG_HAVE_OPROFILE=y

Just make it work, I don`t care the oProfile version. I enclosed building log, both of them.

I am anticipating your reply.

Best Regards,
Ryan

The error message in the oprofile_v1_0.log is:

/usr/lib/libbfd.so: error adding symbols: File in wrong format

It looks like an issue due to the cross compile (target is mips, but the host is x86_64). Is looks like the compiler is trying to link it /usr/lib/libbfd.so rather than

You might take a look at how cross compile was done for arm on the following threads as a examples:
