autogen.sh error: dirname missing operand + autotools not detected

[Mukulkanojia123]

Bug Description

While running ./autogen.sh after successfully executing synclibs.sh, the script fails with the following errors:

dirname: missing operand
Try 'dirname --help' for more information.
Unable to find autotools

---

🔁 Steps to Reproduce

1. Clone the repository
2. Run ./synclibs.sh (runs successfully)
3. Run ./autogen.sh
4. Observe the error

---

Environment

• OS: Windows
• Shell: MINGW64 (Git Bash)
• GCC Version: 6.3.0 (MinGW)

---

Additional Output

which: no aclocal in (PATH...)

---

Expected Behavior

autogen.sh should run successfully and generate the required configuration files.

---

Actual Behavior

The script fails due to:

• dirname: missing operand
• Autotools (e.g., aclocal, autoconf, automake) not being detected

---

Possible Cause

• Missing autotools dependencies (autoconf, automake, libtool)
• Or a variable being passed empty to dirname inside the script

---

Request

Please confirm:

• Required dependencies for Windows/MINGW64 setup
• Whether additional setup steps are needed for autotools
• Or if there's an issue in the script handling empty variables
