Yes, LC_COLLATE=C also works. I used LC_ALL=C because that was the
only options discussed in sort --help and man.
You can test this by extracting some bits of code from src/doc/Makefile.in:
wspage@linux-24ag:~/fricas> export EXAMPLES='ALIST ARRAY1 ARRAY2
BBTREE BINARY BOP BSTREE CARD CARTEN CCLASS CHAR CLIF COMPLEX
CONTFRAC CYCLES DECIMAL DERHAM DFLOAT DMP EQ EQTBL EXIT EXPR
FARRAY FILE FLOAT FNAME FPARFRAC FR FR2 FRAC GBF GSTBL HEAP
HEXADEC INT INTHEORY KAFILE KERNEL LAZM3PK LEXP LEXTRIPK LIB LIST
LODO LODO1 LODO2 LPOLY LWORD MAGMA MAPPKG1 MATRIX MKFUNC MPOLY
MSET NONE OCT ODPOL OP OVAR PERMAN PFR POLY QUAT QUAT2 RADIX
RECLOS REGSET ROMAN SEG SEGBIND SET SINT SQMATRIX SREGSET STBL
STREAM STRING STRTBL SYMBOL TABLE TEXTFILE UNISEG UP VECTOR VOID
WUTSET XPBWPOLY XPOLY XPR ZDSOLVE ZLINDEP'
wspage@linux-24ag:~/fricas> (for a in ${EXAMPLES}; do echo $a; done;
sed -n 's/^)abb[a-z]* [a-z][a-z]* *\([A-Z0-9][A-Z0-9]*\) *\([^
]*\)/\1 \2/p' src/algebra/*.spad.pamphlet ) | sort -k1,1
On my OpenSuSE system this outputs a long list, but notice in
particular the sort order:
...
FIELD Field
FILE
FILECAT FileCategory
FILE File
FINAALG FiniteRankNonAssociativeAlgebra
FINITE Finite
FINRALG FiniteRankAlgebra
FLAGG2 FiniteLinearAggregateFunctions2
FLAGG FiniteLinearAggregate
FLALG FreeLieAlgebra
FLASORT FiniteLinearAggregateSort
FLINEXP FullyLinearlyExplicitRingOver
FLIOUFUN FloatLiouvilianFunctions
FLOAT
FLOATCP FloatingComplexPackage
FLOAT Float
FLOATRP FloatingRealPackage
FM2 FreeModuleFunctions2
FMCAT FreeModuleCategory
FMC FortranMatrixCategory
FM FreeModule
FMFUN FortranMatrixFunctionCategory
FMONOID FreeMonoid
FMTC FortranMachineTypeCategory
FNAME
FNAME FileName
FNCAT FileNameCategory
...
The rest of the script
wspage@linux-24ag:~/fricas> (for a in ${EXAMPLES}; do echo $a; done;
sed -n 's/^)abb[a-z]* [a-z][a-z]* *\([A-Z0-9][A-Z0-9]*\) *\([^
]*\)/\1 \2/p' src/algebra/*.spad.pamphlet ) | sort -k1 | awk
'{if(a==$1){print};a=$a}' | sort -k2
is intended to pick out only those abbreivations that actually occur
in the EXAMPLES list but the awk filter fails to do this because of
the assumptions it makes about the sort order.
...
EXIT Exit
FR2 FactoredFunctions2
FNAME FileName
FARRAY FlexibleArray
FPARFRAC FullPartialFractionExpansion
QUAT2 GeneralQuaternion
GSTBL GeneralSparseTable
GBF GroebnerFactorizationPackage
HEAP Heap
HEXADEC HexadecimalExpansion
...
Notice in particular that FILE and FLOAT are missing (among many others).
The use of the option LC_ALL=C or LC_COLLATE=C corrects the problem
wspage@linux-24ag:~/fricas> (for a in ${EXAMPLES}; do echo $a; done;
sed -n 's/^)abb[a-z]* [a-z][a-z]* *\([A-Z0-9][A-Z0-9]*\) *\([^
]*\)/\1 \2/p' src/algebra/*.spad.pamphlet ) | LC_COLLATE=C sort -k1,1
| awk '{if(a==$1){print};a=$a}' | sort -k2
---
The problem appears near the end of in the FriCAS build when
secmenu.awk is called
HTEX2SECMENU = ${AWK} -f ${srcdir}/secmenu.awk
...
${HD_EXAMPLES_MENU_FILES}: tmp/%.menu: ${htexsrcdir}/%.htex examples.list
mkdir -p tmp
# ${HTEX2SECMENU} SRC CHAPTERNUMBER SECTIONNUMBER MENUDIR
${HTEX2SECMENU} $< ${EXAMPLES_CHAPTER_NO_LEADING_ZERO} `sed -n
'/^$* /=' examples.list` tmp > $@
This use of sed to construct one of the arguments of secmenu.awk is
very fragile and fails because some expected entries are missing from
the 'examples.list' file that was constructed above. As a result awk
tries to write a file into the root / directory and fails (assuming
that you are not running this as root)!
