[hermitguo]

Describe the bug

ubuntu 24.04.04 + cpu: Intel(R) Xeon(R) Platinum 8488C

export SRC_ROOT=/data/software
export INST_ROOT=/data/usr

/modules-5.6.1$ source $INST_ROOT/modules-5.6.1/init/bash
ERROR: this extension is compiled for Tcl 9.0
while executing
"load [file normalize [getConf tcl_ext_lib]] Envmodules"

To Reproduce

Steps to reproduce the behavior:

1. install tcl 9.0.3
tar -xf tcl9.0.3-src.tar.gz && cd tcl9.0.3/unix

mkdir build && cd build

../configure --prefix=$INST_ROOT/tcl9.0.3 \
    --enable-shared \ 
    CFLAGS="-O3 -march=sapphirerapids -fPIC" \
    LDFLAGS="-Wl,-rpath=$INST_ROOT/tcl9.0.3/lib"

make -j$(nproc) && make install

2. install  modules 5.6.1
tar -xf modules-5.6.1.tar.gz && cd modules-5.6.1

./configure --prefix=$INST_ROOT/modules-5.6.1 \
    --with-tcl=$INST_ROOT/tcl9.0.3/lib \
    --with-tclinclude=$INST_ROOT/tcl9.0.3/include \
    CFLAGS="-O2 -fPIC"

make -j$(nproc) && make install
3.

Expected behavior

The source $INST_ROOT/modules-5.6.1/init/bash will not fail,
and my can use tcl9.0.3

Thanks for your report @hermitguo

It feels like the tclsh command used to evaluate $INST_ROOT/modules-5.6.1/libexec/modulecmd.tcl is coming from a Tcl version 8.6 (maybe the one installed on your system natively).

I suggest you add the following option when running the configure script:

--with-tclsh=$INST_ROOT/tcl9.0.3/bin/tclsh9.0
