Openssl native client port gives error on building

问题:

I am working on a simple chrome NaCl extension where I want to use the openssl library for encryption of data. I checked out the pepper_40 branch of naclports as described on the wiki page and tried to build the port for openssl but it is encountered with the following error.

kunal@Baweja:~/Downloads/naclports/src$ ./make_all.sh openssl
+ set -e
+ TARGETS=openssl
+ TARGETS=openssl
+ BUILD_FLAGS=--ignore-disabled
+ export TOOLCHAIN
+ export NACL_ARCH
+ export BUILD_FLAGS
+ NACL_ARCH=x86_64
+ TOOLCHAIN=glibc
+ make openssl
bin/naclports install openssl --ignore-disabled
Already installed 'openssl' [x86_64/glibc/release] 
+ TOOLCHAIN=newlib
+ make openssl
bin/naclports install openssl --ignore-disabled
Building 'glibc-compat' [x86_64/newlib/release] 
naclports: Building glibc-compat: failed.
make: *** [openssl] Error 1

What could be the possible error exactly and any ways around that ?

回答1:

Thanks to @sbc for telling me about VERBOSE=1 option in the comment on the above question. I identified that the libstdc++.so.6 file was missing while accessing from $NACL_SDK_ROOT/tools/sel_ldr_x86_32. This is so because my machine is of x86_64 type i.e. 64 bit. Hence we need to install libstdc++ for 32 bit machines separatly by using the command sudo apt-get install lib32stdc++6

The original solution to missing libstdc++.so.6 file is given here
