Build failed for a baremetal

Sanu5 over 1 year ago

hello,

While I am trying to execute a simple bubble sort program in c as provided as an example in the arm development studio IDE, I am facing 3 errors like as shown below: (Target and source must be capability)

/bubblesort.c:45:37: error: invalid target type 'uint32_t *' (aka 'unsigned int *') for __cheri_tocap: target must be a capability
seq_t sequence = (__cheri_tocap seq_t)malloc(sizeof(uint32_t) * SEQ_LEN);

../bubblesort.c:57:33: error: invalid source type 'uint32_t *' (aka 'unsigned int *') for __cheri_fromcap: source must be a capability
free((__cheri_fromcap void*)sequence);

/bubblesort.c:70:6: error: conflicting types for 'print'
void print (seq_t __cheri_input sequence, int size) {

N.B: I am using LLVM 13.0.0 with Morello support.

Many thanks, Kevin for the information. Once I apply the script to generate the elf as shown in line no 25 (script shown below), the elf is generating but I am not sure once I try to view the elf file by right-clicking and viewing through the elf content editor it displays that it is not a valid elf file.

ok so is this version correct? changed line 24 with $PROGRAM_NAME.elf after -o and in line 25 used $PROGRAM_NAME.elf as first argument instead of the second as shown below.
