Hi,
Hi, I'm trying to install the QT5.15.2 package using the help of BLFS 11.1 book but it won't work. When i launch ./configure for the first time i get the error: after looking for the error i got that i need to do and export of a MAKE variable. So i did no w when i do ./configure i get the next error:
When i i get
and i don't see any x86_64-pc-linux-gnu in qtbase/mkspecs so until now i'm thinking the issue might be coming from there?
I also installed all the required and recommended packages.
Thanks in advance for the help!

Did you complete the post-lfs config tasks?

I’ve built Qt many many times using blfs jhalfs with no issues (just this weekend in fact)…

I tried to redo it. It doesn't change the issue. I have a hunch that qt installation doesn't understand my BLFS architecture.

I have a hunch it’s an issue with your build environment.

What does “which make” return?

I had to install which first, it returns

Ok how about echo $PATH

do you have symbolic link setup for sh? what does which sh show?

have you installed all qt dependencies? the dependency tree is pretty convoluted

LFS links /bin/sh to bash.

In my experience BLFS is very good at correctly listing immediate dependencies (which in turn will list theirs). Admittedly I've never tried to build and install anything as complicated as Qt.

i actually built qt5 twice this weekend, once for xfce and again for gnome using blfs jhalfs. takes about 160 minutes on my dell e6510 laptop. i actually wouldn’t recommend building by hand as the dependency tree is quite convoluted with some circular dependencies.

what i would recommend is to get blfs jhalfs running and use it to build qt5 and its dependencies. what i do is select qt5 then find out what dependencies need built, then start slowly resolving them. i don’t build anything in blfs jhalfs without first understanding why, and verifying the configuration in the book, as sometimes the build scripts have stuff you don’t need and can break the build. i usually limit my blfs jhalfs build passes to less than five or so packages.

why are you getting Blocked C code on cloudflare in your error message? what does line 225 of the configure script say?

i checked line 225 in my qt5 configure script and it is a function calling awk. since you couldn’t find make and presumably can’t find awk i suspect there is a problem with your path

It shows which sh shows As i thought it is an architecture problem. I recompiled the kernel and i copied x64 architecture this time. And as far as it is going configure is working well.
Thanks all for your help!

Moin,

In my experience, "which" is a command, which needs to be installed pretty soon during building BLFS. If it is not, very subtile problems may happen, if "which" is not found by scripts like configure, etc.
So your problem may have it's cause by not having which intstalled "early" enough on your system.

cheers,
WK
