All three also do `pkg-config --cflags libusb-1.0`, but omap3-usb-loader doesn't actually use it and assumes that <libusb-1.0/libusb.h> will resolve to something that's correct. I've also run into downstream patches around broken toolchains that change <libusb.h> to <libusb-1.0/libusb.h>, so the header is found. Fix the first issue and workaround the broken toolchains by using GCC 5.0+ __has_include to fallback to <libusb-1.0/libusb.h> if it doesn't exist or if GCC is older than 5.0.

How does this become a problem exactly?

This is pretty much what you get with autoconf configure scripts when you put headers in a non-standard place and don't have .pc files setup to find them.

I ran twice into downstream patches patching imx-usb-loader. So apparently -lusb1.0 was returned but the CFLAGS were correctl set. > If it's the latter, then I'll point out that my previous email would > let someone put CROSS_LIBUSB_CFLAGS=-I<cross-include-dir>/libusb-1.0 > on the make command line and get a build without having .pc files. > This is pretty much what you get with autoconf configure scripts when > you put headers in a non-standard place and don't have .pc files setup > to find them.

I wrote this patch initially to support a pkg-config less build: If CROSS_PKG_CONFIG wasn't set (no default), we would just use -lusb-1.0 and hope it works. For the header __has_include would try the two paths that most probably would work. Now that I dropped that fallback, I should probably drop this patch as well and let people with broken pkg-config files just fix their brokenness. >> +++ b/scripts/libusb.h > > By naming this libusb.h, it requires that "libusb.h" find this file > and <libusb.h> find a different header of the same name.

We already have some target tools, but support for those is easier, because they don't link against libraries. We use pkg-config to get cc and ld flags, but we always assume that pkg-config is for the host system and there is no well-defined way to request pkg-config for the target system. Support this by introducing a new CROSS_PKG_CONFIG. This will be consulted only for target tools and default to $(CROSS_COMPILE)pkgconfig.

Since pkgconfig was only used for host tools, I didn't need to make both host and target pkgconfig work. But of course that will no longer be true after this patch. There is a problem with only supplying CROSS_PKG_CONFIG. To get both host and target pkgconfig to work, I also need to supply the env variables used by pkgconfig, PKG_CONFIG_SYSROOT and PKG_CONFIG_LIBDIR. The former makes the paths returned by pkgconfig correct and the latter controls which set, target or host, of .pc files will be used. Maybe something like this in the Makefile: CROSS_PKG_CONFIG ?= $(CROSS_COMPILE)pkg-config CROSS_PKG_CONFIG_SYSROOT ?= $(PKG_CONFIG_SYSROOT) CROSS_PKG_CONFIG_LIBDIR ?= $(PKG_CONFIG_LIBDIR) CROSS_PKG_CONFIG_ENV := \ PKG_CONFIG_LIBDIR=$(CROSS_PKG_CONFIG_LIBDIR) \ PKG_CONFIG_SYSROOT=$(CROSS_PKG_CONFIG_SYSROOT) HOST_LIBUSB_CFLAGS := $(shell $(PKG_CONFIG) --cflags) CROSS_LIBUSB_CFLAGS := $(shell $(CROSS_PKG_CONFIG_ENV) $(CROSS_PKG_CONFIG) --cflags) Then use those everywhere someone wants the libusb cflags. Repeat for LDFLAGS. You'll get fewer repeated invocations of pkg-config this way too. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 12+ messages in thread

You can set these on the environment before starting barebox build.

The problem is they need different values for the target and for the host version of the package config. The way you have done this it is only possible for there to be one value that is used both when the host version is called and the same values when the cross pkg-config is called. > > The former makes the paths returned by pkgconfig correct and the > > latter controls which set, target or host, of .pc files will be used. > > > > Maybe something like this in the Makefile: > > > > CROSS_PKG_CONFIG ?= $(CROSS_COMPILE)pkg-config > > CROSS_PKG_CONFIG_SYSROOT ?= $(PKG_CONFIG_SYSROOT) > > CROSS_PKG_CONFIG_LIBDIR ?= $(PKG_CONFIG_LIBDIR) > > CROSS_PKG_CONFIG_ENV := \ > > PKG_CONFIG_LIBDIR=$(CROSS_PKG_CONFIG_LIBDIR) \ > > PKG_CONFIG_SYSROOT=$(CROSS_PKG_CONFIG_SYSROOT) > > > > HOST_LIBUSB_CFLAGS := $(shell $(PKG_CONFIG) --cflags) > > CROSS_LIBUSB_CFLAGS := $(shell $(CROSS_PKG_CONFIG_ENV) > > $(CROSS_PKG_CONFIG) --cflags) > > > > Then use those everywhere someone wants the libusb cflags.

Linux allows you to build the tools individually, e.g. for tmon we have this: make -C $(LINUX_DIR)/tools CC=$(TARGET_CC) PKG_CONFIG_PATH=$(STAGING_DIR)/usr/lib/pkgconfig tmon Can Barebox build do this? This way there are multiple make calls, with different options, to build a kernel for the target, dtc for the host, tmon for the target, and so on. So Linux build may not be an ideal pattern to copy. It can not build a tool for both host and target in one build. > > You'll get fewer repeated invocations of pkg-config this way too. > > Ye, I thought about that as well, but we do it like this for the host tools, > so I left it for now. It's not much overhead and it makes it a bit easier > to follow what is used. It looks like Linux build assigns pkg-config output to a variable in every instance but dtc's build. I think the existing Barebox makefiles are just a bit sloppy in how they call pkg-config. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 12+ messages in thread
