Can we assume a chmod is present ? So on Linux:
$ set -x; touch a.out; chmod +x a.out; test -x; echo $?
+ touch a.out
+ chmod +x a.out
+ test -x
+ echo 0
0
and on MSYS:
$ set -x; touch a.out; chmod +x a.out; test -x a.out; echo $?
+ set -x
+ touch a.out
+ chmod +x a.out
+ test -x a.out
+ echo 1
1
Or is something as simple as this, first on Linux:
$ set -x; echo "test" > a.exe; test -x a.exe; echo $?
+ echo test
+ test -x a.exe
+ echo 1
1
and on MSYS:
$ set -x; echo "test" > a.exe; test -x a.exe; echo $?
+ set -x
+ echo test
+ test -x a.exe
+ echo 0
0
I understand that MSYS
has a problem, but I don't know that Cygwin does. Does Cygwin have
the problem? If not, then the test is incorrect.
It may have the problem if the file-system is FAT32 rather than NTFS. An RTEMS
user reported Cygwin worked once he changed from FAT32 to NTFS.
