Openssl doesn't get built in when build called from qemu.mk #705

Closed schnorea closed 11 months ago

schnorea commented 11 months ago

Openssl doesn't seem to get built on unmodified build.

Problem

After running make qemu.mk and successfully getting Normal and Secure World xterm windows. The Normal World doesn't seem to have openssl in fact all that can be found of openssl is

# find | grep -i openssl
./etc/ssl/openssl.cnf
./etc/ssl/openssl.cnf.dist

All other operations of the environment (as the tutorial in the docs mention) work as advertised.

Desired State

My ultimate goal is to have optee as the keystore for openssl via pkcs11 to workout how this might be used for code signing, etc. For this I will need at least to be able to access openssl.

Context

This build environment is sourced from optee/build repo directly via this script (along with other elements)

#!/bin/bash
echo "This will take some time, since it's cloning lots of code ..."
yes "" | repo init -u https://github.com/OP-TEE/manifest.git
repo sync -j6

Make target: qemu.mk Build environment: Docker container. - Build qemu.mk version of systems using this docker file https://github.com/jbech-linaro/docker_optee

Attempted Debug

common.mk has openssl enabled

BR2_PER_PACKAGE_DIRECTORIES ?= y
BR2_PACKAGE_LIBOPENSSL ?= y
BR2_PACKAGE_MMC_UTILS ?= y
BR2_PACKAGE_OPENSSL ?= y
BR2_PACKAGE_OPTEE_BENCHMARK_EXT ?= $(CFG_TEE_BENCHMARK)
BR2_PACKAGE_OPTEE_BENCHMARK_EXT_SITE ?= $(BENCHMARK_APP_PATH)
BR2_PACKAGE_OPTEE_CLIENT_EXT_SITE ?= $(OPTEE_CLIENT_PATH)
BR2_PACKAGE_OPTEE_EXAMPLES_EXT ?= y
BR2_PACKAGE_OPTEE_EXAMPLES_EXT_CROSS_COMPILE ?= $(CROSS_COMPILE_S_USER)
BR2_PACKAGE_OPTEE_EXAMPLES_EXT_SDK ?= $(OPTEE_OS_TA_DEV_KIT_DIR)
BR2_PACKAGE_OPTEE_EXAMPLES_EXT_SITE ?= $(OPTEE_EXAMPLES_PATH)

Other elements from the config show up as would be expected but not openssl.

In looking through the build of the rootfs.cpio.gz It looks like that config makes its way to the out-br/defconfig file via the python script here.

.PHONY: buildroot
buildroot: optee-os optee-rust
    @mkdir -p ../out-br
    @rm -f ../out-br/build/optee_*/.stamp_*
    @rm -f ../out-br/extra.conf
    @$(call append-br2-vars,../out-br/extra.conf)
    @(cd .. && $(PYTHON3) build/br-ext/scripts/make_def_config.py \
        --br buildroot --out out-br --br-ext build/br-ext \
        --top-dir "$(ROOT)" \
        --br-defconfig build/br-ext/configs/optee_$(BUILDROOT_ARCH) \
        --br-defconfig build/br-ext/configs/optee_generic \
        --br-defconfig build/br-ext/configs/$(BUILDROOT_TOOLCHAIN) \
        $(DEFCONFIG_GDBSERVER) \
        $(DEFCONFIG_XEN) \
        $(DEFCONFIG_TSS) \
        $(DEFCONFIG_TPM_MODULE) \
        $(DEFCONFIG_FTPM) \
        --br-defconfig out-br/extra.conf \
        --make-cmd $(MAKE))
    @$(MAKE) $(br-make-flags) -C ../out-br all

After this I lose my way in the make started by the python script and the one that follows below it.

Help

Any guidance or suggestion on why this shouldn't work and how to make it work welcome.

It looks like you need to set BR2_PACKAGE_LIBOPENSSL_BIN=y to get the openssl binary.

Thank you that did it! How could I have discover this myself in the future for other libraries/utilities? Does make menuconfig highlight these dependencies?
