Hi, all Although PoCC is optional, I want to give it a try. But I have a problem while building PoCC. Here is the error, ---------------------------------------------------------- make[1]: Entering directory `/tmp/chenwj/pocc-1.0-rc3.1/optimizers/letsee-0.2.0-pre/letsee' make[2]: Entering directory `/tmp/chenwj/pocc-1.0-rc3.1/optimizers/letsee-0.2.0-pre/letsee' /bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I../letsee/include/letsee -I.. -I.. -I../letsee/include -I../letsee/include +-I/tmp/chenwj/pocc-1.0-rc3.1/math/install-fm/include -I/tmp/chenwj/pocc-1.0-rc3.1/analyzers/install-candl/include +-I/tmp/chenwj/pocc-1.0-rc3.1/driver/install-pocc/include -I/tmp/chenwj/pocc-1.0-rc3.1/math/install-piplib/include +-I/tmp/chenwj/pocc-1.0-rc3.1/ir/install-scoplib/include -g -O2 -MT dependence.lo -MD -MP -MF .deps/dependence.Tpo -c -o dependence.lo dependence.c ../libtool: line 827: X--tag=CC: command not found ../libtool: line 860: libtool: ignoring unknown tag : command not found ../libtool: line 827: X--mode=compile: command not found ../libtool: line 994: *** Warning: inferring the mode of operation is deprecated.: command not found ../libtool: line 995: *** Future versions of Libtool will require --mode=MODE be specified.: command not found ../libtool: line 1138: Xgcc: command not found ../libtool: line 1138: X-DHAVE_CONFIG_H: command not found ../libtool: line 1138: X-I.: command not found ../libtool: line 1138: X-I../letsee/include/letsee: No such file or directory ../libtool: line 1138: X-I..: command not found ../libtool: line 1138: X-I..: command not found ../libtool: line 1138: X-I../letsee/include: No such file or directory ../libtool: line 1138: X-I../letsee/include: No such file or directory ../libtool: line 1138: X-I/tmp/chenwj/pocc-1.0-rc3.1/math/install-fm/include: No such file or directory ../libtool: line 1138: X-I/tmp/chenwj/pocc-1.0-rc3.1/analyzers/install-candl/include: No such file or directory ../libtool: line 1138: X-I/tmp/chenwj/pocc-1.0-rc3.1/driver/install-pocc/include: No such file or directory ../libtool: line 1138: X-I/tmp/chenwj/pocc-1.0-rc3.1/math/install-piplib/include: No such file or directory ../libtool: line 1138: X-I/tmp/chenwj/pocc-1.0-rc3.1/ir/install-scoplib/include: No such file or directory ../libtool: line 1138: X-g: command not found ../libtool: line 1138: X-O2: command not found ../libtool: line 1138: X-MT: command not found ../libtool: line 1138: Xdependence.lo: command not found ../libtool: line 1138: X-MD: command not found ../libtool: line 1138: X-MP: command not found ../libtool: line 1138: X-MF: command not found ../libtool: line 1138: X.deps/dependence.Tpo: No such file or directory ../libtool: line 1138: X-c: command not found ../libtool: line 1191: Xdependence.lo: command not found ../libtool: line 1196: libtool: compile: cannot determine name of library object from `': command not found make[2]: *** [dependence.lo] Error 1 -------------------------------------------------------------- Any idea?
