I have a Fortran program and I compiled it with gfortran, like what follows, gfortran -mmacosx-version-min=10.14.3 -ffixed-line-length-none -c ../main_tools/thermal_ellipsoid.f90 gfortran -o thermal_ellipsoid thermal_ellipsoid.o The compiled executable thermal_ellipsoid is working fine locally. However, when I tried to sign the executable using codesign, it was failing. Here follows is the command I used to sign the executable, codesign -f --timestamp -o runtime -v --sign 'Developer ID Application: XXXXX' thermal_ellipsoid and here is the error I got, ./thermal_ellipsoid dyld[45718]: Library not loaded: /usr/local/opt/gcc/lib/gcc/current/libgfortran.5.dylib Referenced from: <37A6CBC1-BFE9-31F0-B397-34A05BBA2B6C> /Users/y8z/Dev/RMCProfile/mac-gfortran/thermal_ellipsoid Reason: tried: '/usr/local/opt/gcc/lib/gcc/current/libgfortran.5.dylib' (code signature in <CF6596E0-B4AA-3AD2-9620-74B6FC158924> '/usr/local/Cellar/gcc/13.2.0/lib/gcc/current/libgfortran.5.dylib' not valid for use in process: mapped file has no cdhash, completely unsigned?

I was trying to follow the steps of signing my library -&gt; submit it for notarization -&gt; staple it. The first two stages show no error but I had some issues with the final stage of stapling. For example, if I want to staple one of my dynamic libraries, as following, xcrun stapler staple --verbose libs/libX11.6.dylib I got the following error, Processing: /Applications/RMCProfile/libs/libX11.6.dylib Properties are { NSURLIsDirectoryKey = 0; NSURLIsPackageKey = 0; NSURLIsSymbolicLinkKey = 0; NSURLLocalizedTypeDescriptionKey = "Unix Executable File"; NSURLTypeIdentifierKey = "com.apple.mach-o-dylib"; "_NSURLIsApplicationKey" = 0; } Props are { cdhash = {length = 20, bytes = 0xbd1e9c1fcae2663f3bb56af9f789557164badd00}; digestAlgorithm = 2; flags = 65536; secureTimestamp = "2021-04-25 22:37:07 +0000"; signingId = "org.xquartz.libX11.6.dylib"; teamId = NA574AWV7E; } JSON Data is { records = ( { recordName = "2/2/bd1e9c1fcae2663f3bb56af9f789557164badd00"; } ); } Headers: { "Content-Type" = "application/json"; } Domain is api.apple-cloudkit.com Certificate trust evaluation did not return expected result.
