Just Sharing: LFS + BLFS compiled mostly with clang

plasmonics · 12-22-2017, 06:52 AM

Glad you got it to work. I did apply some of those patches, but maybe not in that sequence. If it is also accepting laTeX input, you must have gotten it to integrate with Texlive.

I will try this procedure.

The only potential problem is I am using gcc-7.2, not 6.x.

I compiled it using gcc-7.2.0 (LFS-8.1 & BLFS-8.1 using gcc-7.2.0).
The patch for gcc-6, but it also works for gcc-7.2.0 (at least for me).

I do not have Texlive.

Using LaTex means using "LaTeX-style input".

Please visit this site:
https://www.abisource.com/release-notes/2.4.0.phtml

You will find this:

Code:

Equations can be inserted using MathML or LaTeX-style syntax. 
Inserting a nice-looking equation is as simple as typing E=mc^2. 
Figure 3 shows an example of a complex equation rendered by AbiWord.

The LaTeX-style input used to produce this figure was:

f(x) = \frac{1}{\sqrt{2\pi\sigma^2}}e^{\frac{-{(x-\mu)}^2}{2\sigma^2}}

So when you click Menu -> Insert -> Equation -> From LaTex, it will open a Text Area.
Copy and paste this text (LaTeX-style)

f(x) = \frac{1}{\sqrt{2\pi\sigma^2}}e^{\frac{-{(x-\mu)}^2}{2\sigma^2}}

input into that Text Area.

It will render the equation on document. It is not visually write a formula like LibreOffice or Microsoft Office.

You can write your own formula to render on document, if you know how to write LaTex style input.

The above is a good tutorial by anak_bawang for setting up equations in Abiword.

When I compiled Abiword earlier, I used different patches than the ones above for gdome2, gmetadom, and gtkmathview. That is probably why the screen rendering was malfunctioning. Now it is working much better.

I added a few more configure options, including latex.

Code:

./configure --prefix=/usr --enable-plugins="collab openxml goffice grammar mathview command loadbindings presentation aiksaurus babelfish freetranslation google kword latex opendocument mswrite paint pdf wikipedia urldict xslfo" --enable-clipart --enable-templates

In addition, to get math font rendering to work better using latex syntax, it is a good idea to install Mozilla's latin modern math and stix fonts from the Abiword home page. Also, install latex-xft-fonts package from the arch linux wiki page. You can place them in separate subdirectories under /usr/share/fonts. Then update the font cache.

Code:

fc-cache -fv

Thanks, that's a brilliant user manual. Only one thing you haven't told us: why use clang in the first place? What are the advantages over gcc? Is it faster? Or is this just to prove that it can be done?

Lost of debate about the advantages of gcc vs clang.
Try googling it with keywords "gcc vs clang".

FreeBSD using clang:
https://mikegerwitz.com/2013/08/Free...ommunity#ref-0

Apple Xcode, starting from Xcode 3.2 using clang
https://developer.apple.com/library/...iew/index.html

Many Debian packages compiled using clang
https://wiki.debian.org/llvm-clang
http://clang.debian.net/

So, for me:
This just to prove that it can be done.
Give me an alternative compiler.

Hi just gonna try this
1 Q openssl

Code:

./config --prefix=/tools             \
         --openssldir=/tools/etc/ssl \
         --libdir=lib

Is that correct or should it be /tools/lib ?

Sorry my bad it follows "prefix"

anak_bawang · 03-01-2018, 09:09 AM

@spiky0011
I used this --libdir=lib
and the library would be in /tools/lib folder.

spiky0011 · 03-04-2018, 01:17 PM

Hi

I,ve not been able to build Pixman-0.34.0. I have looked through Makefiles and tried different things, do you have the configure you used?

Try this

Code:

./configure --prefix=/usr --disable-static --disable-libpng

Had some problems too, but this work for me.
Tried some patch for libpng, but none works.

plasmonics · 03-05-2018, 06:04 AM

Are you using Clang to compile pixman, or gcc?

Using gcc, I just cut and paste the instructions in the book. No errors. Same with libpng. No patch used other than the one in the book.

As the thread title "Just Sharing: LFS + BLFS compiled mostly with clang",
so I tried to compile any source using clang.
Only when the source can not be compiled by clang, then I changed to gcc.

I was referring to post#23. It was not clear if the poster had used clang.

spiky0011 · 03-05-2018, 10:30 AM

Yes plasmonics tried with clang, it builds fine with gcc.

Thanks anak_bawang.

Oh Sorry, I was looking at the thread order. Forgive me.

I've also been building LFS with clang lately, but have also taken a step forward to use llvm's standard libraries instead of gcc supplied ones (compiler-rt instead of libgcc, libc++ instead of libstdc++ and openmp instead of libgomp), and have found out that pixman needs a following sed after configure to build with clang v5:

sed -i "/HAVE_GCC_VECTOR_EXTENSIONS/d" config.h
