Build successful on x86_64, runs in linuxu and kvm.

How did you build it, what application did you use, did you make calls to functions exposed by the library?

[nelsongillo]

Extending app-helloworld with minimal example using pcre_compile and pcre_exec: build and run successful

Sample Code:

re = pcre_compile (regex, 0, &error, &erroffset, 0);
if (!re)
{
    printf("pcre_compile failed (offset: %d), %s\n", erroffset, error);
    return -1;
}

unsigned int offset = 0;
unsigned int len    = strlen(str);
rc = pcre_exec(re, 0, str, len, offset, 0, ovector, OVECTOR_SIZE);

if (rc == 1) {
    printf("Valid!\n");
} else {
	printf("Not Valid!\n");
}

@EinzigartigerName , this doesn't work for me. I'm using the latest Unikraft version and I get the following error when running the building and running a Unikernel image using minimal_pcre_test.c:
