When I compile with ./gcc-arm-linux-gnueabihf-4.7-master/bin/arm-linux-gnueabihf-g++ -c Steph.cpp on an Ubuntu Linux 16.04 machine which already has gcc 5.3.1 installed:

I get the error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

even though I specify what the LD_LIBRARY_PATH is. Using strace, I verified that the libstdc++.so.6 at LD_LIBRARY_PATH is recognized and read.

I am using the GitHub download of gcc-arm-linux-gnueabihf-4.7-master. Does it have an install script which I forgot to do?

How do I fix this error?

The reason I ask this question is I want to cross compile with an ARMv6 forward compatible comilper a simple example using a shared library which is scheduled for testing on an Raspberry PI ARMV6 emulator Wheezy mounted on a SD card.

Earlier today I compiled the same simple example on an ARMv7 compiler, arm-linux-gnueabihf-g++ version 5.3.1 installed on the same Ubuntu Linux computer hosting a Raspberry PI arm v6 emulator installed on SD card mounted in an USB adapter and got Segmentation Fault when I ran this simple ARMV7 example's executable on this particular emulator.

  • @goldilocks, Thanks for the great edit. Could I ask you how to fix the following error messages: ./Downloads/tmp/usr/bin/../lib/gcc/arm-linux-gnueabihf/4.6/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lgcc_s and Downloads/tmp/usr/bin/../lib/gcc/arm-linux-gnueabihf/4.6/../../../../arm-linux-gnueabihf/bin/ld: cannot find -lgcc Do these errors have anything to do with collect2 and bash shell export LD_LIBRARY_PATH? – Frank May 4 '16 at 14:23
  • I enjoy cross-compiling anything beyond the kernel about as much as I enjoy cross-country running, which is very little but I'll do it when I have to -- so I'm not much help with this. I hope you understand the reason for the edit was "my problem is urgent" is a general no-no on SE. I would try and get a preliminary clue or answer about this on S.O., keeping in mind normal pi images seem to have a bit of weird thing going on with paths and core library bits (which makes the kernel easy, because it is statically linked). – goldilocks♦ May 4 '16 at 14:32
  • @goldilocks, Thanks for your reply a few minutes ago. I will post another question about this subject now. – Frank May 4 '16 at 14:44
  • I found out through trial and error that cannot find -lgcc can be fixed using --sysroot=file_path where libgcc.so can be found in the file_path. However -lgcc_s appears not to be sensitive to --sysroot. Does anyone now how to fix cannot find -lgcc_s? Thank you. – Frank May 4 '16 at 19:21
  • @goldilocks, Here is the new question you suggested I ask earlier this morning. raspberrypi.stackexchange.com/questions/46878/… – Frank May 4 '16 at 22:49

There is most likely a bug in linaro 4.7 about LD_LIBRARY_PATH. Instead, I used this link, http://packages.ubuntu.com/precise/amd64/g++-4.6-arm-linux-gnueabihf to solve the cannot load shared object libstdc++.so.6, no such file bug.

  • Could a knowledgeable person tell me the installation steps for packages.ubuntu.com/precise/amd64/g++-4.6-arm-linux-gnueabihf? Thank you. – Frank May 4 '16 at 15:23
  • Please accept your own answer with a click on the tick on its left side. Only this will finish the question and it will not pop up again year for year. – Ingo Dec 17 '19 at 15:51
