I have an alpine running container which contains some binaries in usr/local/bin
When I ls the content of usr/local/bin I got this output :
/usr/local/bin # ls
dwg2SVG dwg2dxf dwgadd dwgbmp dwgfilter dwggrep dwglayers dwgread dwgrewrite dwgwrite dxf2dwg dxfwrite
Which is what I expected.
However if I execute one of these binaries by calling it I got a not found error from the shell :
/usr/local/bin # dwg2dxf
sh: dwgread: not found
/usr/local/bin # ./dwg2dxf
sh: ./dwgread: not found
I tested my $PATH which seems to be correct :
/usr/local/bin # echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
How can I make those binaries callable or "foundable" ? Did I miss something in my Dockerfile build ?
I suppose that there is something with the ldconfig command in alpine that went wrong but I'm not sure.
EDIT
As suggested in one answer here I executed the file command and here is the output :
/usr/local/bin # file dwg2dxf
dwgread: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=7835d4a42651a5fb7bdfa2bd8a76e40096bacb07, with debug_info, not stripped
Thoses binaries are from the LibreDWG Official repository as well as the first part of my Dockerfile. Here is the complete Dockerfile :
