Cannot compile irqbalance @ glibc


I'm trying to build the current master build with:

gcc v8.2, glibc, -O2, binutils 2.32

System: Arch Linux (latest).

I have spotted this issue and added the three lines into the Makefile.

No luck. Log is showing not much:

Haven't yet looked into it.
Sounds like glibc somehow expects full intl libs unlike musl.
(I have never compiled with glibc, so no experience with its quirks.)

You might test adding the typical include line to the Makefile.


That site dislikes adblockers...

But that linker problem sounds like a probable culprit.

(The stupid things here is that irqbalance does not really require much complex text functions, especially as we have disabled the GUI components. And generally we "disable NLS".)

I have a feeling it's due to glib2. With the 2.64.2 update, -lintl gets added through pkgconfig.

You could resolve this particular error by including libintl-full in your build configuration. You'll need to add the line PKG_BUILD_DEPENDS:=libintl-full to the top of the Makefile to get it to build libintl and put the into your staging directory before it tries to build irqbalance (I should have added this line, but since I always had it in my config, the build system seems to build it first anyway and I didn't notice the omission).

[EDIT: I think you'll need to make that PKG_BUILD_DEPENDS:=gettext-full as the build system uses the directory name rather than the package name in the PKG_BUILD_DEPENDS line]

This error only occurred because of the dependencies and the lines you added which I referred to in the issue I posted on github. If it was not compiling before you added these lines, then you have a different problem.

So, first can you compile it using the vanilla Makefile and post any errors (and the config.log if the configure script errors out).

I've been using a heavily customized x86_64 version of Openwrt with glibc for years (first with 15.05 and now with 19.07.2).

The truth is that quite a few packages on Openwrt experience compilation problems and dependency issues when using glibc. Probably because few people are using it due to the difficulties of getting everything built, and so few problem reports are made.

In fact, the current version of 19.07.2 kernel panics on x86_64 with the included version of glibc so I had to bump to 2.30, which in itself required a whole bunch of supplemental patches to make it work.

Hauke implemented similar patches for 2.31 which I think has been pushed to master already, although the packages feed has not been patched with anything, so people trying to build using glibc are likely to experience problems with a number of packages.

I use glibc since I have a bunch of stuff that requires it and also since I favour speed over size: my router is an 8-core C3758 SoC with 16GB of RAM and 250GB of SSD, so I don't care about the space/bloat.

I just did a full clean and build, which I had not previously done when compiling irqbalance and got another error this time. Not sure why this error didn't pop up when I just added irqbalance as a module to an already built system.

I needed to add the following patch to fix it as it's assuming that it's linking against the libiconv stub, which is only there if CONFIG_PACKAGE_libiconv is selected, whereas it should link against the full libiconv.a if CONFIG_PACKAGE-libiconv-full is selected.

I'll add this as an issue on github

I still wonder if the original issue mentioned by @pwned and also @dl12345 was caused by clibc or glib2

@pwned @dl12345
Do you intentionally set the full NLS in your build?
Or do you run otherwise just vanilla config, but just have glibc instead of musl?

You error about "lintl" suggests that you have at least partianlly NLS enabled, and I wonder if that in intentional, or if that is just caused by using glibc (like the topic title suggests).

1 Like

Yeah, earlier there was no glib2 dependency, but the upgrade to 1.6.0 caused the inclusion of that library. As only a few functions are needed, the library is linked statically so that only the needed parts get linked in.

That has caused the line STAGING_DIR)/usr/lib/libiconv-stub/lib/libiconv.a

You are right, that prevents using the full NLS version.

The best solution would likely be to use include/ in the Makefile like @neheb suggests, and modify the line accordingly, to reference to $(ICONV_PREFIX) instead of the stub

You might test if that fixes it for you.

I haven't really worked with the NLS stuff as none of apps that I use, require NLS functionality.

I'm just adding:


I do this since I compile OpenWrt by myself. I always used glibc. Because I prefer standards (not because of the "speed"). IMO size does not matter anymore for devices >= Midrange (not exactly I know :wink: ). And yes I'm aware that more code means higher security risks.
Over time I almost always had minor issues like this compiling with glibc. But only minor things like this nls issue. But I never had any issues with codepages before. I do this as a habit since decades (not specific for OpenWrt). For OpenWrt it's not necessary. The only usecase would be writing proper filenames to mounted external drives.
For this case I decided to write sth. Just to indicate that the patch is not working as intended. If there is no fix available I will drop nls for getting irqbalance working.

as there is already the include, you could try changing the
as sets that according to the NLS status.

I am more interested on your generic OpenWrt config than on the irqbalance logs (as the package just reacts to your toplevel settings or packages.
Is NLS enabled in your OpenWrt config?
What does ./scripts/ show?

Hi hnyman,

thx for reply. I compiled irqbalance again with your modification only. As far as I can see the errors are exactly the same.

config diff (as you requested):

config.log/compile.log (new)


My last build with exactly (only made a defconfig for this new build) the same diff as above was:
No issues with irqbalance or glibc at this time.

Yes, intentionally set to full NLS

Ok, so I've done some more testing.

Firstly, the reason that the compile did not fail with the inconv-full vs iconv-stub issue on my system initially is that there are two packages, procps-ng and dovecot that both have the line PKG_BUILD_DEPENDS:=libiconv, without checking whether iconv-full is set or not.

Because I have package procps-ng selected, libiconv-stub was incorrectly built and present in my staging area. However, after cleaning the system, since procps-ng only got built after irqbalance, libiconv-stub was not there. Hence the error in the clean build case.

So procps-ng and dovecot will need to be modified to check which version of libiconv is being used.

Then, the errors with irqbalance. They're all glib2 functions calling routines in pthread or libintl.

ICONV_PREFIX is actually the full path, so that won't work. The line would need to read $(ICONV_PREFIX)/lib/libiconv.a

The following fixed it correctly for me [EDIT: the DEPENDS:= line should also be made conditional on libiconv-stub vs libiconv-full; I omitted that in the patch below`

Actually, looking at it has all the necessary definitions added to TARGET_LDFLAGS already, so the following looks much cleaner adds to PKG_BUILD_DEPENDS appropriately, so the line in the Makefile should just be modified slight to add rather than overwrite it.

Just for reference. I'm not choosing nls directly on purpose. It's choosen e. g. by filesystem modules which I supplemented with additional languages only.

I have compiled my config from abvoe just without the package "irqbalance" (not a solution I know). But there were no errors. So for my setup there is no crossreference from other packages.
