Use /usr/ccs/bin/nm. Relevant to AIX 3.2.5 which has +# another version under /usr/ucb/bin/nm. +# 2. Use the -B flag to have a standard BSD representation +# of the symbol list on both AIX 3.2.5 and AIX 4. The "-B" +# flag is missing in the AIX 3.2.5 online usage help of 'nm'. +# 3. Use the -x flag to have a hex representation of the symbol +# values. This fills the leading whitespaces on AIX 4, +# thus simplifying the sed statement. +# 4. Eliminate all entries except those with either "B", "D" +# or "T" key letters. We are interested only in the global +# (extern) BSS, DATA and TEXT symbols. With the same statement +# we eliminate object member lines relevant to AIX 4. +# 5. Eliminate entries containing a dot. We can have a dot only +# as a symbol prefix, but such symbols are undefined externs. +# 6. Eliminate everything including the key letter, so that we're +# left with just the symbol name. +# +/usr/ccs/bin/nm -Bex $inputFiles \ +| sed -e '/ [^BDT] /d' -e '/\./d' -e 's/.* [BDT] //' \ +| sort | uniq >> $expFileName |
