Tried to used shc mixed with makeself and the result are small binary files compared with the original makeself scripts.

To test it:

wget https://josm.openstreetmap.de/josm-tested.jar
mkdir files
mv josm-tested.jar files/
echo '#!/bin/sh' > files/run.sh
echo 'java -jar ./josm-tested.jar' >> files/run.sh
chmod u+x files/run.sh
makeself files test.run "test" ./run.sh

Now the file 'test.run' works ok. Just go and apply some shc magic:

shc -rT -f ./test.run 
shc: WARNING!!
   Scripts of length near to (or higher than) the current System limit on
   "maximum size of arguments to EXEC", could comprise its binary execution.
   In the current System the call sysconf(_SC_ARG_MAX) returns 2097152 bytes
   and your script "./test.run" is 8400754 bytes length.

Well, is a warning. Lets take a look at the filesizes:

du -sh test.run test.run.x
8,1M    test.run
28K test.run.x

Where did the data go?

On latest version of Cygwin:

~/shc/shc-3.8.9
$ make test
*** Compiling script "match"
CFLAGS="-Wall " ./shc -v -f match
shc shll=sh
shc [-i]=-c
shc [-x]=exec '%s' "$@"
shc [-l]=
shc opts=
shc: cc -Wall match.x.c -o match.x
match.x.c:260:24: fatal error: sys/ptrace.h: No such file or directory
#include <sys/ptrace.h>
^
compilation terminated.
./shc: No error
makefile:43: recipe for target 'match.x' failed

make: * * * [match.x] Error 1

How do we solve this?

To duplicate, compile match.x first:

 make
  make test

Verify it works:

$ ./match.x bash
/usr/bin/bashbug
/bin/bash
/bin/rbash
...

Now put that into shell scripts:

$ echo ./match.x bash > /tmp/test.sh

$ sh -x /tmp/test.sh
+ ./match.x bash
/bin/sh: 0: Can't open bash

[Update]:

Seems that shc-3.8.9 is hard wired to bash -- everything bash works whereas everything Bourne shell (sh) won't work:

$ cat /tmp/test-sh.sh
#!/bin/sh
./match.x bash

$ /tmp/test-sh.sh
^C

I.e., scripts with Bourne shell (sh) Shebang will hung until break.

However, everything bash works. I.e. both bash -x /tmp/test.sh and the following script work:

$ cat /tmp/test-bash.sh
#!/bin/bash
./match.x bash

Thanks to Jahidul Hamid (neurobin) finding that out.

UPDATE:

Please note that the bug reported here has been fixed.

If it is still happening to you, please do a strace as normal user and compare with the two traces posted here. If it's the same as Nick777818's -- the wait4 Operation was not permitted, or anything else,

please open another bug rather than following up here.

Original question:

I got "Operation not permitted" when trying to to run "make test", like this:

$ ./match.x sh
./match.x: Operation not permitted
Killed

Here are the details:

~/prj/shc-3.8.9$ make
make: *** No rule to make target shc.c', needed byshc'. Stop.

~/prj/shc-3.8.9$ ln -s shc-3.8.9.c shc.c
