If we are using v0.15.2 release uftrace for your yocto BSP in a glibc-based environment, we can write bitbake file.
I have done BSP and tested on Digilent ZYBO 77-20 Board.
I writed bb
on project-spec/meta-user/recipes-apps/uftrace/uftrace_0.15.2.bb
SUMMARY = "Trace and analyze execution of a program written in C, C++, Rust and Python"
HOMEPAGE = "https://github.com/namhyung/uftrace"
BUGTRACKER = "https://github.com/namhyung/uftrace/issues"
SECTION = "devel"
LICENSE = "GPL-2.0-only"
LIC_FILES_CHKSUM = "file://COPYING;md5=b234ee4d69f5fce4486a80fdaf4a4263"
DEPENDS = "elfutils"
inherit autotools
SRCREV = "9d8657e90b918994d7d2bcf6dd2cc7354c35a1b4"
SRC_URI = "git://github.com/namhyung/${BPN};branch=master;protocol=https"
S = "${WORKDIR}/git"
def set_target_arch(d):
import re
arch = d.getVar('TARGET_ARCH')
if re.match(r'i.86', arch, re.I):
return 'i386'
elif re.match('armeb', arch, re.I):
return 'arm'
else:
return arch
EXTRA_UFTRACE_OECONF = "ARCH=${@set_target_arch(d)} \
with_elfutils=/use/libelf/from/sysroot"
do_configure() {
${S}/configure ${EXTRA_UFTRACE_OECONF}
}
FILES_SOLIBSDEV = ""
FILES:${PN} += "${libdir}/*.so"
COMPATIBLE_HOST = "(i.86|x86_64|aarch64|arm|riscv64)"
# uftrace supports armv6 and above
COMPATIBLE_HOST:armv4 = 'null'
COMPATIBLE_HOST:armv5 = 'null'
After performs the BSP on ZYBO Z7-20, we can test uftrace it works well.
NOTE: If someone using musl
c library, We can reference https://github.com/openembedded/meta-openembedded/tree/master/meta-oe/recipes-devtools/uftrace
