Hi:

 

trying to setup NodeJS 10.7.0 on AIX 7.2

https://nodejs.org/dist/v10.7.0/node-v10.7.0-aix-ppc64.tar.gz

 

Since we are using Go lang on AIX, we have gcc 8.x and libstdc++ 8.x libraries

 

However with NodeJS 10.x, the requirement is libstdc++ 6.x

As a workaround, we are exploring the following approach

• download libstdc++ 6.x ppc RPM
• extract it in a directory co-located with the directory where NodeJS has been extracted
• update LIBPATH to reflect the path which has 6.x shared libraries
• if ldd ./node works then we are good to go

Fortunately, with a bit of exploration i found the following discussion thread

https://github.com/nodejs/build/issues/925

 

All seems good, until i execute the following command

rpm2cpio ibstdc++-6.3.0-1.aix7.2.ppc.rpm 
| cpio -idmv

The output generated is

cpio: 0511-903 Out of phase!
         cpio attempting to continue...
 cpio: 0511-904 skipping 522454 bytes to get back in phase!
         One or more files lost and the previous file is possibly corrupt!

cpio: 0511-027 The file name length does not match the expected value.

 

This is rather unusual as the RPM file is complete and not corrupt.

Any pointers as to what i could be missing here ?

 

warm regards

Saifi.

gcc-6 and should be compatible with gcc-8, we haven't seen any major compatibility issue.

 

Please use /usr/linux/bin/cpio command to extract the rpm files, you can get this command from cpio rpm package present on AIX Toolbox.

 

Thanks,

NodeJS 10.7.0 works fine with libstdc++ 8.x in the limited set of scenarios that i have programmed in.

Perhaps the issues may be seen, once i start developing Node Add-ons in C++.

$ ldd node 
node needs:
         /usr/lib/libperfstat.a(shr_64.o)
         /opt/freeware/lib64/libstdc++.a(libstdc++.so.6)
         /opt/freeware/lib64/libgcc_s.a(shr.o)
         /usr/lib/libpthreads.a(shr_xpg5_64.o)
         /usr/lib/libc.a(shr_64.o)
         /usr/lib/libcfg.a(shr_64.o)
         /usr/lib/libodm.a(shr_64.o)
         /unix
         /usr/lib/liblvm.a(shr_64.o)
         /usr/lib/libcorcfg.a(shr_64.o)
         /usr/lib/libc.a(shr.o)
         /usr/lib/libcrypt.a(shr_64.o)
         /usr/lib/libsrc.a(shr_64.o)
         /usr/lib/libcrypt.a(shr.o)

thanks for the pointer about gcc6.x and gcc8.x compatibility.
