[yocto] libgcc_s not present in Yocto image

[Nathan Sowatskey]

Hi Ross

Many thanks for following up. Fred also offered some helpful suggestions in a different thread.

The program in question was supplied to me by a third party for testing, so I shall obscure the name here and call it testprog.

It was installed by:

dpkg -i ./testprog.deb 


Where the .deb file was supplied to me. I don’t know what that was built on though.

Then:

which testprog 
/usr/bin/testprog
/usr/bin/testprog 
-sh: /usr/bin/testprog: No such file or directory

Then I:

readelf -a /usr/bin/testprog | grep Shared
 0x0000000000000001 (NEEDED)             Shared library: [libsnmp.so.30]
 0x0000000000000001 (NEEDED)             Shared library: [libQt5Network.so.5]
 0x0000000000000001 (NEEDED)             Shared library: [libQt5SerialPort.so.5]
 0x0000000000000001 (NEEDED)             Shared library: [libQt5Core.so.5]
 0x0000000000000001 (NEEDED)             Shared library: [libstdc++.so.6]
 0x0000000000000001 (NEEDED)             Shared library: [libgcc_s.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libpthread.so.0]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]

Followed by:

find /usr/lib -name libQt5Network.so.5
/usr/lib/libQt5Network.so.5

So, I have that lib.

find /usr/lib -name libgcc_s.so.1     
root at qemux86-64:~# 

I don’t have that lib.

With ldd I get:

ldd /usr/bin/testprog 
/usr/bin/ldd: line 117: /usr/bin/testprog: No such file or directory

So, that’s where I am at this stage.

Regards

Nathan
