avr-gcc: configure: error: cannot compute suffix of object files: cannot compile

[seanmeir@…]

I tried to

sudo port install avr-gcc

on,

Darwin qi 11.4.0 Darwin Kernel Version 11.4.0: Mon Apr  9 19:32:15 PDT 2012; root:xnu-1699.26.8~1/RELEASE_X86_64 x86_64

and I keep getting the error,

configure: error: cannot compute suffix of object files: cannot compile

main.log attached.

I just updated to 2.1.1 and the same error occurred.

On my 10.7 system avr-gcc can be built (and as far as I tested it, it generates code that is identical to what a Linux cross compiler emits).

On my other 10.7 systems, avr-gcc builds fine, but on this machine I get the error.

I don't know anything about Apple's LLVM versioning but I find it strange that I have the older Xcode and a seemingly newer LLVM gcc backend.

Did you download the current command line tools via Xcode?

At least this web page ​http://wiki.osdev.org/Talk:GCC_Cross-Compiler#On_Mac_OS_X_Lion claims that an apparently similar error is caused by the LLVM code generator.

Well, I'm completely lost on that one, it looks like a bug in LLVM! On the other hand, I have the same version of llvm-gcc, and I can build it successfully... :/

Replying to titus@…:

My command line tools came from Xcode. I didn't manually install them, or get them from somewhere else (I think).

Starting with the appbundled Xcode (>=4.3) you have to manually / explicitely install them.

The dialog is in Preferences - Downloads - Components. There you would have an "Install" (or "Update", IIRC) button next to "Command Line Tools."

BTW, on another machine I have Xcode 4.3.2 and gcc LLVM version 2336.9.00.

There, in the download dialog it does not show a button for the "Command Line Tools" but says "Installed".

So I'd guess that you have installed the newer Xcode but did not update the CLTs.

I will check if I can build avr-gcc on that machine.

[titus@…]

On my aforementioned second machine avr-gcc builds ok.

I did a port selfupdate / upgrade outdated before I tried. All newer ports necessary for gcc (mpfr, and the like) were downloaded as binary packages.

Hello... What's the status here? Did it eventually build?

Having the same issues as above running Lion 10.7.4 on MacBook Air. Installed fine on an old iMac (2006) running exact same OS. On the MBA I get the familiar configure error:

configure: error: cannot compute suffix of object files: cannot compile

I've run all the appropriate port updates, cleaned the avr-gcc build and tried again. Not sure what details will help, though.

Up to now, it still looks like an issue depending on the "LLVM build" version. It seems that 2336 is OK, and 2335 is broken.

Or did I miss something?

BTW, does it now build OK on the build bot?

[g5pw (Aljaž Srebrnič)]

Yes, it looks like an issue with the host compiler... Please update to the latest Xcode Command Line tools and retry! It does indeed build OK on the bot, or, at least, I haven't received any error reports by the buildbot...

It's been two months, I assume this ticket is closed. If the problem still presents itself, feel free to reopen it!
