Problem description
Clang produces strange linking errors when trying to link readline program.
$ clang test.c -lreadline

clang-8: error: linker command failed with exit code 1 (use -v to see invocation)
Steps to reproduce
-
Make sure your device running Android OS v5.x (just android-5 packages isn't enough).
-
Put following content to test.c:
#include <stdio.h>
#include <stdlib.h>
#include <readline/readline.h>
#include <readline/history.h>
int main(int argc, char** argv)
{
char* buf;
while ((buf = readline("$ ")) != NULL) {
if (strlen(buf) > 0) {
add_history(buf);
}
printf("echo [%s]\n", buf);
free(buf);
}
return 0;
}
clang test.c -lreadline
Expected behavior
Program should be compiled successfully.
