Hi Tim,
at Debian, a certain build issue of magic was found:
Consider building scmos.tech, built like this, according to the log:
[...]

Now, looking at source and resulting files:
scmos.tech.in:
=================================================================
[...]
/* ---------------------------------------------------------------- */
/* Well */
/* ---------------------------------------------------------------- */
/* 1.1 */
/* Now use "edge" for width DRC... A test only for rule1 */
/* Other rules may follow in the near future... */
#ifdef SUBMICRON
edge4way (~nwell)/w nwell 12 nwell nwell 12\
"N-Well width must be at least 12 (MOSIS rule #1.1)"
edge4way (~pwell)/w pwell 12 pwell pwell 12\
"P-Well width must be at least 12 (MOSIS rule #1.1)"
#else
edge4way (~nwell)/w nwell 10 nwell nwell 10\
"N-Well width must be at least 10 (MOSIS rule #1.1)"
edge4way (~pwell)/w pwell 10 pwell pwell 10\
"P-Well width must be at least 10 (MOSIS rule #1.1)"
#endif
[...]
=================================================================
scmos.tech:
=================================================================
[...]
# 960 "scmos.tech.in"
edge4way (~nwell)/w nwell 10 nwell nwell 10
"N-Well width must be at least 10 (MOSIS rule #1.1)"
edge4way (~pwell)/w pwell 10 pwell pwell 10
"P-Well width must be at least 10 (MOSIS rule #1.1)"
[...]
=================================================================
Looks like the gcc (4.7.2-5 in Debian) preprocessor just discards the "\"
line endings instead of interpreting as line continuations, resulting in
broken resulting files, as reported below.
Is this a known issue?
Please see also http://bugs.debian.org/698760 and please tell how we
can help debugging this.
Thanks in advance,
Roland
