Re: [ptxdist] Build U-Boot against host-openssl fails
Hello Michael,
I tried building the same U-Boot 2022.04 for a different board in a different
BSP now, which uses ptxdist 2021.06 already. This works at least somehow. More
comments below.

Adding this or not would make a difference in build behaviour if U-Boot would
not have that fallback in its Makefile.
If it's present '…/platform-v7a/sysroot-host/bin/pkg-config' is used.
If it's _not_ present '…/platform-v7a/sysroot-cross/bin/pkg-config' is used.
So it seems to be the right thing from a rule file point of view to add this.
I will send a patch.

With ptxdist 2021.06 and setting both of those to 'yes', build is successful.
(Note: At least U-Boot 2022.04 and 2022.07 are buggy and do not allow to build
with CONFIG_TOOLS_LIBCRYPTO disabled and host libssl-dev absent [1].)

Did not try with libssl-dev installed on the host again. It should work
against host-openssl package from ptxdist, otherwise I would consider it
broken anyways.

Still gives:
HOSTLDLIBS_mkimage is -lssl -lcrypto
Even does that if I remove the '|| echo "-lssl -lcrypto"' fallback, so that's
probably a good thing. (Is empty with removed fallback without the U_BOOT_PATH
fix from above, then build fails.)

Added this line in U-Boot source tools/Makefile to see what's going on:
$(info HOSTLDLIBS_mkimage is $(HOSTLDLIBS_mkimage))
(directly after that is assigned)
Output is:
HOSTLDLIBS_mkimage is -lssl -lcrypto

Yeah well, it was late yesterday, what the barebox package does is setting
_PATH and I tried that already (as written before). So I tried calling
pkg-config with that path the same way the U-Boot Makefile does (redacted):

Sorry, I wanted to paste the actual part from tools/Makefile (u-boot
source) and this is it:
174 # MXSImage needs LibSSL
175 ifneq
($(CONFIG_MX23)$(CONFIG_MX28)$(CONFIG_ARMADA_38X)$(CONFIG_TOOLS_LIBCRYPTO),)
176 HOSTCFLAGS_kwbimage.o += \
177 $(shell pkg-config --cflags libssl libcrypto 2> /dev/null || echo "")
178 HOSTLDLIBS_mkimage += \
179 $(shell pkg-config --libs libssl libcrypto 2> /dev/null || echo "-lssl
-lcrypto")
180
181 # OS X deprecate openssl in favour of CommonCrypto, supress deprecation
182 # warnings on those systems
183 ifeq ($(HOSTOS),darwin)
184 HOSTCFLAGS_mxsimage.o += -Wno-deprecated-declarations
185 HOSTCFLAGS_image-sig.o += -Wno-deprecated-declarations
186 HOSTCFLAGS_rsa-sign.o += -Wno-deprecated-declarations
187 endif
188 endif
I'm not sure how I can verify what's actually called here?
Just had another look at what buildroot does. Seems like
host-pkg-config is required, IIRC that was not used by ptxdist. Not
sure how I can let ptxdist use host pkg-config, but I hope I'll find
out tomorrow.

This sounds like u-boot is calling /usr/bin/pkg-config instead of
.../sysroot-host/bin/pkg-config (and not the cross pkg-config either).
Maybe /usr/bin/pkg-config is called explicitly with the whole path
somewhere? That could be a "feature" to avoid the cross pkg-config when
cross-compiling.

[ptxdist] Build U-Boot against host-openssl fails
Hei hei,
although claiming it's optional latest U-Boot versions require OpenSSL on the
host.¹ I added an option to build host-openssl with commit
0c779a60e50c40d522b1e9c20b5c75b2e57fde5a ("u-boot: Add option to depend on
host-openssl") but ptxdist u-boot package still fails to link to host openssl
package, message is always missing some openssl symbols.
I tried the same thing as barebox now in rules/u-boot.make like this:
+# use host pkg-config for host tools
+U_BOOT_PATH:= PATH=$(HOST_PATH)
This does not help.
I'm somehow suspecting the wrong pkg-config is called. Affected is not the
target image, but the host tools (like mkimage) built alongside with the
target stuff (which you 1) can not disable to build and 2) need for certain
parts of the ptxdist package anyways, so not building those is no option).
I tried each combination of PTXCONF_U_BOOT_NEEDS_HOST_OPENSSL and
CONFIG_TOOLS_LIBCRYPTO in U-Boot kconfig, all fail.
buildroot has a fix for building against host-openssl, but I don't understand
it, and I'm not sure if the same approach would work in ptxdist.
Any ideas?
(Disclaimer: this only happens on a quite recent U-Boot, e.g. from 2022.)
(More disclaimer: it does not happen if libssl-dev is installed on the build
host.)

¹ I consider this a bug, and I'm not the only one, but several attempts to fix
this in upstream U-Boot did not lead to merge any fix.
