[Mono-dev] 2.4RC3 build problems (and code problems with the build)

[Paul]

Hi,

I'm a tad worried about the build problems on mono. Looking at the
throwback and comments coming from the compiler, I'm seeing lots of
these sorts of problems which indicates bison problems and quite a lot
of warnings while compiling the likes of boehm-gc.c (gc_priv.h line 1931
- warning function declaration isn't a prototype - lots of these) and
also a bit later on

../doltcompile gcc -DHAVE_CONFIG_H -I. -I.. -I/usr/include/glib-2.0
-I/usr/lib/glib-2.0/include    -DGC_LINUX_THREADS -D_GNU_SOURCE
-D_REENTRANT -DUSE_MMAP -DUSE_MUNMAP -D_FILE_OFFSET_BITS=64
-D__mono_ppc__ -DUSE_COMPILER_TLS  -O2 -g -pipe -Wall
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m32 -fno-strict-aliasing -fno-strict-aliasing
-Wdeclaration-after-statement -g -Wall -Wunused -Wmissing-prototypes
-Wmissing-declarations -Wstrict-prototypes  -Wmissing-prototypes
-Wnested-externs -Wpointer-arith -Wno-cast-qual -Wcast-align
-Wwrite-strings -MT jni.lo -MD -MP -MF .deps/jni.Tpo -c -o jni.lo jni.c
jni.c:490: warning: function declaration isn't a prototype
jni.c:494: warning: no previous prototype for 'ikvm_MarshalDelegate'
jni.c:501: warning: no previous prototype for 'ikvm_CallOnLoad'
mv -f .deps/jni.Tpo .deps/jni.Plo

a load more of the same sort of warnings in macros.c, serial.c,
zlib_macros.c and minizip/zip.c

and finally before System.Xml.dll throws a big style wobbler,

make[8]: Entering directory
`/builddir/build/BUILD/mono-2.4/mcs/class/System.XML'
./../../jay/jay -ct < ./../../jay/skeleton.cs System.Xml.XPath/Parser.jay >System.Xml.XPath/Parser.cs
./../../jay/jay: 21 rules never reduced
./../../jay/jay: 1 shift/reduce conflict, 42 reduce/reduce conflicts.
sed "s/\%start Expr/\%start Pattern/" System.Xml.XPath/Parser.jay >Mono.Xml.Xsl/PatternParser.jay
echo "#define XSLT_PATTERN" > Mono.Xml.Xsl/PatternParser.cs
./../../jay/jay -ct Mono.Xml.Xsl/PatternParser.jay < ./../../jay/skeleton.cs >>Mono.Xml.Xsl/PatternParser.cs
./../../jay/jay: 3 rules never reduced
./../../jay/jay: 1 shift/reduce conflict, 46 reduce/reduce conflicts.

These conflicts are the most worrying and is more than likely the cause
for the ppc build to fail.

I'm not sure if this is a bison style problem but it is worrying that
the likes of not checking a return value for fwrite when building mcs to
start with is still being overlooked.

I would suggest that before 2.4 hits the roads properly, these issues
are carefully looked at (that is unless I'm needlessly worrying, but
given that the likes of the gcc people stop when these problems occur
suggests otherwise).

TTFN

Paul
