Re: 'libstdc++.so.6' cannot be found in RUNPATH ()

Hi Pierre!

thank you for the input. I've made the changes as suggested.
Sadly it does not help, I'm getting the same behavior.

Inside the environment-variables I can see the gcc-5.4.0-lib listed:

export LIBRARY_PATH="/gnu/store/bzn4wyrbdmfc1bd7lq05db5psfl5f8x8-perl-5.26.0/lib:/gnu/store/6hicns85s8ddp0y539wdspwx22ac2kmv-bzip2-1.0.6/lib:/gnu/store/g3nari57wcfnm00kv9bnpyzdzfq4h8pk-xz-5.2.2/lib:/gnu/store/msw2q7nr3vfmgwyxf15y0x7qbngs9y3d-file-5.30/lib:/gnu/store/9pq16kfcldqqcbd58mmfp37g3awhg4sd-gawk-4.1.4/lib:/gnu/store/nnykzgwfy8mwh2gmxm715sjxykg8qjwn-binutils-2.28/lib:/gnu/store/n6nvxlk2j8ysffjh3jphn1k5silnakh6-glibc-2.25/lib:/gnu/store/y31sxrygd9ifpxra06bmlx8c52gbydd4-glibc-utf8-locales-2.25/lib:/gnu/store/mpa86gcr3wk7yzvbdxc58j5vddqcs3w0-epics-base-3.15.5/lib:/gnu/store/j9rxwf40xw2r5drycijl4l25l4bja8qv-epics-asyn-R4-33/lib:/gnu/store/f0m8rdd0vv0gdddi2grpcb5swxd5zp2f-epics-busy-R1-7/lib:/gnu/store/61fcp65n6jvaz2hyzy31im408h5a79yl-epics-autosave-R5-9/lib:/gnu/store/s55cw29248kzl3c61vgawb4csrbkivry-epics-calc-R3-7/lib:/gnu/store/6dv72pq83gv7y2qxk60rasa2dqjr2nmm-epics-sscan-R2-11/lib:/gnu/store/a35yjr26wizmj7vbxbf2s8x3p6g7hb4m-epics-seq-R2-2-6/lib:/gnu/store/gs898mgcbzi0zx5wikylz0zrb756mg75-epics-adsupport-R1-4/lib:/gnu/store/i4vqyz44pa31iypwbq06zvw52yk2jmlg-epics-adcore-R3-2/lib:/gnu/store/mipizipnr4y2hly9b429j8id1albbgqi-readline-7.0/lib:/gnu/store/2rzp2py00609lvkh977bfyxja7wd5idx-gcc-5.4.0-lib/lib:/gnu/store/09j7scnl3hahcmql986fsjpzj6gqsmzv-ncurses-6.0/lib"

Let me point out that the library depending on libstdc++.so.6 does not get compiled, nor does the package use it in anyway. What I'm getting at is that since libstdc++.so.6 is not actually referenced by the package in any way (though the failing lib), can it be that that gcc-5.4.0-lib gets stripped away somewhere along the way?

Thanks!
Hinko

Hi Hinko!

Packaging is done in a sandboxed environment that is totally independent of your
installation.
So you don't need to install gcc at all.

You don't need to propagate the input either, because the end-user only cares
about the package, not the dependent libraries.

Last, you seem to have forgotten the version in the input.

Try with the following line instead:

    (inputs
      `(("gcc:lib" ,gcc-5 "lib")))

Hope that helps.
