You may freely use, modify and/or distribute this file.

For a high-level overview of building TeX Live, see
http://tug.org/texlive/build.html.

To configure and make the source tree, run ./Build.
To build (mostly) without optimization, run ./Build --debug.
To make without configuring, run TL_CONFIGURE=true ./Build.

(Nearly everything the Build script does can be overridden via
environment variables; just take a look to see all the names.)

Prerequisites:
- GNU make.  If your GNU make is invoked by some name other than `make',
 try setting the envvar TL_MAKE to what is needed.

- GNU clisp and GNU libffcall, must be present for xindy.  See more
 details in utils/README.  (Alternative: Build --disable-xindy.)

- libfontconfig (again both headers and library) must be present for
 XeTeX and xdvipdfmx, except on MacOSX.  (Alternative:
 Build --disable-xetex --disable-xdvipdfmx.)

- X11 headers and libraries must be present for pdfopen and xdvi.
 (Alternative: Build --without-x.)

- If you modify any .y or .l source files, then Bison and Flex (or maybe
 equivalents) are needed.  The distributed .c and .h files are generated
 with bison-2.4.3 and flex-2.5.35.

The binaries will be left in ./inst/bin/<stdplatform>.
For TeX Live, ignore the other files and directories that end up in ./inst.

The new binaries are not directly usable from that location.  Instead,
copy them to Master/bin/<tlplatformname>/.

That should be it for normal builds.  Email [email protected] if problems.

To make a usable TeX installation, you have to have (thousands of)
support files as well as the binaries that are built here.  The support
files are maintained completely independently.  The best basis for
dealing with them is the TeX Live (plain text) database,
Master/tlpkg/texlive.tlpdb, and/or our installer.  More information is
under Master/tlpkg.  See also http://tug.org/texlive/distro.html.

For unusual situations:

- If your C++ needs to find the standard library in, say, /usr/local/lib,
(i.e., configure fails saying the compiler doesn't work), try:
env LD_OPTIONS=-R/usr/local/lib ./Build

- Running ./reautoconf here reruns auto-tools as needed.  Use --help for more.


Build information:
 In general, xe(la)tex and xdvipdfmx depend on fontconfig.
 We cannot statically link it because it varies on different systems.

 - you have to set the ulimit high enough before compiling clisp and texlive
     ulimit -s 16384
   did suffice for me
 - compiling of texk/web2c/pdftexdir/writezip.c is broken and triggers a
   compiler error with the above gcc. Disabling optimization -O2 using
   Build --debug ... resolved this problem.
 - compilation of clisp needs hand adding -lavcall -lcallback -ltrampoline
   -lvacall after the -lsigsegv
 - asy compilation with --disable-gsl && make
