You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

	// gcc -o try-catch-ex try-catch.c try-catch-ex.c

	{
	int i = 101;

	printf("before try block...\n");

	// compare relative performance of tolower_ctype, tolower_openbsd, tolower_oraz functions
	// result: 30.80, 30.51, 38.09
