Adding the attached patch that is derived from your changes above, I
got the expected error
../imx53/main.cc: In function ‘int main()’:
/plain/krishna/src/genode/genode_staging.git/repos/os/src/server/tz_vmm/spec/imx53_qsb/../imx53/main.cc:143:21:
error: ‘O_WRONLY’ was not declared in this scope
int fd = open("x", O_WRONLY | O_CREAT);
tz_vmm in its virgin version in our repositories does not use the libc
and, therefore, can't use the file system as you described. Please
provide us with a working patch for Genode 15.08 or Git branch on
GitHub as we otherwise can't reproduce your issue.
Regards
