ROOT Version: 6.30
Platform: Ubuntu / Gitlab CI/CD
Dear ROOT support,
I am struggling with the compilation of a small project I am writing which uses ROOT. It works fine within a custom container that was provided to me by a colleague, but not when using a “standard” ROOT container (concretely, rootproject/root:6.30.04-ubuntu22.04). I assume it’s because some flags are not set up properly, but I am rather lost here.
The MakeFile looks as follows:
include ../standard.mk
# Target executables
TARGET_SELECTOR = SelectorFromJSON
SRC_FILES_SELECTOR = SelectorFromJSON.cc $(PREFIX)/Utils/Parser.cc
OBJ_FILES_SELECTOR = $(SRC_FILES_SELECTOR:%.cc=$(OBJ_DIR)/%.o)
all: $(TARGET_SELECTOR)
# Linking (compilation rule in standard.mk)
$(TARGET_SELECTOR): $(OBJ_FILES_SELECTOR)
$(CXX) $(CXXFLAGS) $(INCLUDES) $(LIBS) -o $@ $^
# Clean rule
.PHONY: clean
clean:
rm -rf $(TARGET_SELECTOR) $(OBJ_FILES_SELECTOR)
where standard.mk looks like:
# Paths and Prefix
PREFIX = $(IRF_DIR)
# Object directory
OBJ_DIR = $(PREFIX)/build
# Include and library directories
INCLUDES = -I$(ROOTSYS)/include -I/usr/include/root/ -I$(PREFIX)
# Library paths
LIBS = -L$(PREFIX)/km3net-dataformat/lib -luuid `root-config --libs`
# Compiler and Flags
CXX = $(shell root-config --cxx)
CXXFLAGS = $(shell root-config --cflags) -Wall -fPIC
# Default object compilation rule
$(OBJ_DIR)/%.o: %.cc
@mkdir -p $(dir $@)
$(CXX) $(CXXFLAGS) $(INCLUDES) $(LIBS) -c $< -o $@
and before running make, I source the following:
#! /bin/bash
if [ -z $ROOTSYS ]; then
echo "ERROR! IRF/setenv.sh environment variable ROOTSYS is not set"
return 1
fi
# Determine the script directory
if [[ -n $BASH_SOURCE ]]; then
# Bash: Use BASH_SOURCE[0]
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
else
# Zsh: Use $0
SCRIPT_DIR="$(cd "$(dirname "$0")" && pwd)"
fi
# Set IRF_DIR
export IRF_DIR="$SCRIPT_DIR"
export LD_LIBRARY_PATH=$IRF_DIR/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH=$IRF_DIR/km3net-dataformat/lib:${LD_LIBRARY_PATH}
I also do source /opt/root/bin/thisroot.sh. But then I see the following error:

Could I get some help figuring out what I am doing wrong? I tried searching the forums, but could not find an answer there.
