It sounds like libpo6 did install. Can you verify this by checking for the presence of /usr/local/include/po6/error.h?

If it does exist, try configuring libe with:

./configure PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

I'm not too familiar with RedHat systems, but I believe they don't always look in /usr/local/ by default

from hyperdex.

O yes!!
Thank you rescrv rescrv rescrv ! it works.
But now have another problem.
I have success install the libe-0.2.5 with code " ./configure PKG_CONFIG_PATH=/usr/local/lib/pkgconfig " .
Then I install hyperdex-0.2b8 with code : " ./configure --enable-python-bindings PKG_CONFIG_PATH=/usr/local/lib/pkgconfig", but have an error , it says:
"
checking for E... no
configure: error: Package requirements (libe >= 0.2) were not met:

No package 'libe' found
"
Thank you for your help~~

from hyperdex.

Can you copy and paste the output you got when you ran make install for libe?

from hyperdex.

the output as follow:

Libraries have been installed in:
/usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:

• add LIBDIR to the `LD_LIBRARY_PATH' environment variable
  during execution
• add LIBDIR to the `LD_RUN_PATH' environment variable
  during linking
• use the `-Wl,-rpath -Wl,LIBDIR' linker flag
• have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for

more information, such as the ld(1) and ld.so(8) manual pages.

I have resolved this problem by the command : "./configure --enable-python-bindings PKG_CONFIG_PATH=/usr/local/lib/pkgconfig E_LIBS=/usr/local/include/e
"
but it show that "
Could not link test program to Python. Maybe the main Python library has been
installed in some non-standard library path. If so, pass it to configure,
via the LDFLAGS environment variable.
Example: ./configure LDFLAGS="-L/usr/non-standard-path/python/lib"

ERROR!
You probably have to install the development version of the Python package
for your distribution. The exact name of this package varies among them.

See `config.log' for more details

"

I have installed Python. I have checked with the order:"python".

Now I am looking for the solution.

from hyperdex.

Would you please attach /usr/local/lib/pkgconfig/libe.pc so that I can fix this issue. It should work with PKG_CONFIG_PATH without needing E_LIBS.

As for the error, you'll need to install the development version of the Python package. For your distribution, it'd probably be python-devel.

Hi,@rescrv, I need your help. Thank you.
I change system to Centos x64,
I success configuare the hyperdex-0.2b8 without error . But When I 'make', the error happen.
