Why would a powershell script behave differently if it was called from Cygwin? -


ls typically run powershell scripts cygwin this:

$ powershell ./scriptname.ps1

it works well, today found instance script fails when called cygwin, succeeds when called powershell. have similar script succeeds in both cases.

this script works both ways:

buildopenssl32.ps1

param ([string]$prefix = $(resolve-path .)) $adjprefix = $prefix -replace "\\",  "/" $prefix32 = "${adjprefix}/win32" new-item -erroraction ignore -itemtype directory -path $prefix32 pushd ${prefix32}/openssl-1.0.2j write-host "building openssl x86 $prefix32 ..." write-host "configuring..." perl configure debug-vc-win32 --prefix=$prefix32 ms\do_nasm write-host "building..." cmd /c "`"${env:vs140comntools}vsvars32.bat`" && nmake /f ms\nt.mak && nmake /f ms\nt.mak install" popd write-host "...done building openssl x86"

this script works when called powershell directly, fails wen called cygwin:

buildopenssl64.ps1

param ([string]$prefix = $(resolve-path .)) $adjprefix = $prefix -replace "\\",  "/" $prefix64 = "${adjprefix}/win64" new-item -erroraction ignore -itemtype directory -path $prefix64 pushd ${prefix64}/openssl-1.0.2j write-host "building openssl x64 $prefix64 ..." write-host "configuring..." perl configure debug-vc-win64a --prefix=$prefix64 ms\do_win64a write-host "building..." cmd /c "`"${env:vs140comntools}../../vc/vcvarsall.bat`" amd64 && nmake /f     ms\nt.mak && nmake /f ms\nt.mak install" popd write-host "...done building openssl x64"

the error looks this:

c:\cygwin64\home\mrixman\openssl5\win64\openssl-1.0.2j>perl ms\uplink-x86_64.pl nasm  1>ms\uptable.asm can't open perl script "ms../crypto/perlasm/x86_64-xlate.pl": no such file or directory

why care how script invocation handled?

edit:

based on error appears, relevant difference in above scripts appears ms\do_nasm vs ms\do_win64a

do_nasm.bat (cygwin friendly)

perl util\mkfiles.pl >minfo perl util\mk1mf.pl nasm vc-win32 >ms\nt.mak perl util\mk1mf.pl dll nasm vc-win32 >ms\ntdll.mak perl util\mk1mf.pl nasm bc-nt >ms\bcb.mak  perl util\mkdef.pl 32 libeay > ms\libeay32.def perl util\mkdef.pl 32 ssleay > ms\ssleay32.def

do_win64a.bat (error when grandparent shell cygwin)

perl util\mkfiles.pl >minfo  cmd /c "nasm -f win64 -v" >nul 2>&1 if %errorlevel% neq 0 goto ml64  perl ms\uplink-x86_64.pl nasm > ms\uptable.asm   # <-- line nasm -f win64 -o ms\uptable.obj ms\uptable.asm goto proceed  :ml64 perl ms\uplink-x86_64.pl masm > ms\uptable.asm ml64 -c -foms\uptable.obj ms\uptable.asm  :proceed perl util\mk1mf.pl vc-win64a >ms\nt.mak perl util\mk1mf.pl dll vc-win64a >ms\ntdll.mak  perl util\mkdef.pl 32 libeay > ms\libeay32.def perl util\mkdef.pl 32 ssleay > ms\ssleay32.def

edit 2:

i created script calls get-childitem env: can @ how powershell environment differs when it's called cygwin (broken) when compared how looks when run start menu (working). converted lowercase case sensitivity mismatch doesn't cause problem.

get-childitem env: diff

for stumbles across post looking answer. have both cygwin (or similar) perl on path before activeperl.

having been looking while, considered being conflicting versions of perl when found comment , 2 previous comments regarding version output on openssl bug tracker. might save others time.
